Matlab Compiler not updating text file

I have a simple text file that I have been including in previous compiled versions of my Matlab program. I recently had to update this text file with addtional text and recompile a new version of the program. However, every time I try to recompile, the compiled installer contains the old version of the text file. I have tried moving the text file to a different location, re-saving the text file, etc then re-compiling. Nothing seems to work. It seems as if Matlab and/or Windows keeps the old text file in some archived state and reverts back to the old version even though the new installer should contain the new one. Any ideas?

Edit: I've tried this with Matlab 2016a and Matlab 2019a and the appropriate compilers. Still seeing the same issue.

There may be another text file with the same name on your path. Try, which -all <filename>.

Thanks for the suggestion - but that's not the case.

which config.txt -all

returned the proper file
