Mojave syncing problem

OK, as of Monday AM the Data Base Properties window is identical for the 2 macs except for

Words: 37,269 994,820
Words: 36,828 962,822

The “Total:” fields are no identical.

Would any ios information be helpful?

Do both Macs use the same versions of macOS?

Correct, 10.14.6

Are the numbers identical after a rebuild (see File > Rebuild Database…)?

I rebuilt the datat base on both machines and this is what I get:

Screen%20Shot%20on%202019-12-02%20at%2011-02-55
Screen%20Shot%20on%202019-12-02%20at%2010-56-36(1)

One group seems to exist only in one database but all the documents should be in both databases. And both the macOS and DEVONthink version are absolutely identical?

Currently:
iphone: 797.4 mb, 1497 files
ipad: 802.3, 1493
