Studio Layout Edit . Tabs/Panel & Sync Views Edit/Detail

Did we miss something along the way?
We have several systems that the change Layouts to Tabs does not work or hold and at the same time does not hold or process the Sync Edit view and Detail View does not hold or work

We waited thinking the Maintenance update would cure this issue We also tried the Github code repair/replace and that did not work.

SuiteCRM 7.9.8 . Now just upgraded
Both on Windows and Ubuntu
Php 7.etc
Maria 10

Any thoughts please we always use Tabs and this is a problem?

Is this the same as your issue?

yes Thanks
I cannot believe the update tat just came out did not fix this old problem
