Dreamweaver 21.4: Code window not displaying correctly. Invisible Code.

I have a recurring problem where Dreamweaver 24.1 is not displaying my code.  Restarting does fix the error, but then my code is already messed up. When typing, it shows me the code that I want, but upon save, I will find that my code is actually a bunch of messed up placements and syntax errors.  I discovered this as I went to copy and paste my code to share with someone and it added extra brackets where there weren't any in my CSS.  I write my own code, I do not use the WYSIWYG design functions, I only view for display. or to copy and paste repeating patterns.

I was cleaning up some old code, converting it to html5.  
Dreamweaver had been running for a long period of time.
I did not take a screenshot, as I really didn't intend to bother anyone about it, but ended up here when looking for a way to clear out my cache, which doesn't seem to be located anywhere one would think it should be, not in AppData locations, not in Program Files, where mine is apparently installed.   I did find some Cache folders, but each file only contained up to 1 KB of data
