Found the problem.....
No idea how, or when, but there was a change made in - au3.keywords.properties
The very last entry in the "au3.keywords.udfs"
In my file, the very last entry was - _word_quit
By removing the trailing "" has corrected the Syntax Folding
Only way to figure this out was to do a fresh install of AutoIt and SciTE on a different machine and compare all the files/folders.
I don't remember making this change/update in this file.
Only noticed the problem on the very last update I ran on AutoIt.
Regardless, this was the problem and fix.
(Auto Indent is also resolved with this fix)
