Buggy behavior when syncing to iCloud

I’m using DTTG on an iPad Pro 10.5. I have ten databases that were synced via local network, and am trying to sync them with iCloud.

When I select or deselect a database for syncing, DTTG randomly selects or deselects other databases. I can get this behavior to repeat consistently.

What can I do to fix it?

A short screencast could be helpful.
If you don’t want to post it here, in DEVONthink To Go, select Help > Contact Us to start a Support Ticket and attach the screencast.

Here’s the video.

I also opened a support ticket so you can review the sync logs.

I don’t see any randomly selected databases in the screencast. It appear the interface is showing an initial state then updating it. This is also shown by databases being marked as local, then updating as Local/Remote.

Development would have to assess this behavior further.
