Contact Provider Extension "enumerateContent" Method Called Multiple Times

I'm facing an issue with the enumerateContent method in my Contact Provider extension. The method is being called multiple times before I call the first observer.didEnumerate..

Here's a sample of my code:

class TestContactProviderRootContainerEnumerator : ContactItemEnumerator {
    let handler = TestContactProviderUsecaseHandler()

    func configure(for domain: ContactProviderDomain) {
        log.error("---> configure")
    }

    func enumerateContent(in page: ContactItemPage, for observer: ContactItemContentObserver) {
        let requestPage = getPageIndex(from: page.offset, pageSize: observer.suggestedPageSize)
        log.error("---> Begin Enumerate Content page=\(requestPage)  pageSize =\(observer.suggestedPageSize)")

        func completion(items: [ContactItem], hasMore: Bool) {
            observer.didEnumerate(items)
            do {
                let generationMarker = try getGenerationMarker(page: page)
                if hasMore {
                    let nextPage = ContactItemPage(generationMarker: generationMarker, offset: page.offset + items.count)
                    log.error("---> nextPage set offset \(page.offset + items.count) nextPage: \(getPageIndex(from: page.offset + items.count, pageSize: observer.suggestedPageSize))")
                    observer.didFinishEnumeratingPage(upTo: nextPage)
                }else {
                    observer.didFinishEnumeratingContent(upTo: generationMarker)
                }
            }catch {
                observer.didFinishEnumeratingContentWithError(error)
                return
            }
        }

        log.error("---> Start Request page=\(requestPage)  pageSize =\(observer.suggestedPageSize)")
        handler.requestForRecordsList(page: requestPage, perPage: observer.suggestedPageSize, sortBy: Field.Contact.lastName, modifiedSince: nil, completion: { contactItems, hasMore, error in
            log.error("---> Finish Request page=\(requestPage)  pageSize =\(observer.suggestedPageSize)")
            if let error {
                log.error("---> Error: \(error)")
                observer.didFinishEnumeratingContentWithError(error)
                return
            }
            completion(items: contactItems, hasMore: hasMore)
            log.error("---> End Enumerate Content page=\(requestPage)  pageSize =\(observer.suggestedPageSize)")
        })
    }
}

Below are the logs that I'm seeing:

---> configure
---> Begin Enumerate Content page=1  pageSize =20
---> Start Request page=1  pageSize =20
---> Begin Enumerate Content page=1  pageSize =20
---> Begin Enumerate Content page=1  pageSize =20
---> Begin Enumerate Content page=1  pageSize =20
....10+times
---> Begin Enumerate Content page=1  pageSize =20
---> Finish Request page=1 pageSize =20
---> Begin Enumerate Content page=1  pageSize =20​​
​---> nextPage set offset 20 nextPage: 2​​
​---> Begin Enumerate Content page=1 pageSize =20
---> Begin Enumerate Content page=1 pageSize =20​
​---> Begin Enumerate Content page=2 pageSize =20
---> Begin Enumerate Content page=2 pageSize =20​
​---> Start Request page=2 pageSize =20​
​---> Begin Enumerate Content page=2 pageSize =20
---> Begin Enumerate Content page=2 pageSize =20​
​....10+times
---> Begin Enumerate Content page=2 pageSize =20
---> Begin Enumerate Content page=2 pageSize =20

Has anyone else experienced this issue? Any ideas on why this is happening or how to fix it.
