Inconsistent Text Sensitive Menu Performance

[ken gray]

I'm having a problem with Microsoft Teams Version 1.5.00.33362 (64-bit) where some of the TS Menu triggers don't erase the trigger text but put in the value just after the trigger text.  However, some do without issue. 

I don't see a common thread between the ones that fail and the ones that don't.  Any ideas on how I can run this to ground?

PS: I have tried with keyboard hooks on and off but same behaviour.
