You should post a sample drawing.

In Autocad 2015, the code worked correctly, in Autocad 2021, 
texts containing control codes are deleted after selection...

It was working OK for me in your sample drawing - I am using 2022 though but would expect any changes in 2021 to be carried through to that.

 

 

Looking at the LISP, there is nothing in there to delete any texts, try loading it last in case there is another LISP loaded with the same name as some of the sub routines and try again maybe
