Here to jump on the bandwagon too- this has been so frustrating! It also has been effecting the way it used to auto-correct misspelled words (it does the same thing, keeps the misspelled word and then the correct spelling, too) , so to me this is indicative of an issue with Zendesk and not solely related to just Text Expander. 
I appreciate they are a separate platform, and we did reach out to see if they had any ideas when this first happened but were unable to support. 
We use Text Expander on every single platform otherwise, and this is just a tedious bummer.
