app name in iCloud "Manage Storage" list is wrong

I have developed the following two App: app1 and app2. Both App have the function of using iCloud. The iCloud container id of app1 and app2 is different. I use the CloudKit storage function of iCloud.

In the storage management of "Settings", iCloud, the display name of app1 is app2's name, not app1's name. This causes many of our users to delete the iCloud data of the application by mistake, resulting in losses.

Now my question is: What caused the name in app1's iCloud storage management list to be displayed as the name of app2? How should it be solved?
