Publisher .420 Beta Character Style Issue

[Wasp11b]

1. Create new document. No need to create text box.

2. Go to Text Styles panel and press button for new character style

3. On list on left ie Style, Character, Font etc, just press any on that list.
4. Now try to go back to Style at the top. You cannot. Cancel.
5. Now File/Close the document.

Repeat steps (1) and (2) above. Now try to go to Style at top of list. It remains inaccessible.

Sometimes doing the above the program crashes without warning, often when testing above using paragraph style.

Doesn't seem to be a problem in .404

Windows 10

I get the exact same result here too.

I can confirm this behavior in .420.
In .404 it works right on my System.

I can repeat the bug in .420 as well. It work as intended in .404
