2020 update for illustator: Issue with getting exact spacing increments

2020 update for Illustrator: Issue with getting exact spacing increment.

With using tabs, can not manually input desired line-up (will not accept change). Same issue with manually inputting spacing from a key object (50% of the time will work if the unit is also typed in  eg:0.25"). Running OS windows 10, this Started after 2020 update. Preferences already have been reset. Anyone able to fix this issue? It is driving me nuts!!

Can you provide a sketch including at least one screenshot with instructions in order to illustrate the issue?

Happens at random for key objects spacing, can upload a screen shot next time it happens. In tabs section you can manually input a number. Right now it shows 19.1" if I were to put in 17" it will stay at 19.1 (tab dragged to that point ). Contacted Adobe, their advice was the style sheets were corrupt ( if a new file opened the tab features work properly), but this happens in all files made in any versions prior to the 2020 update. Any help is appreciated, been using illustrator since 2001 so do have some experience 🙂 .

I will try to reproduce that tomorrow and inform you about the results as soon as I can.
