When writing for--- it will change it to fro---- no matter the words spelling

I don’t know why but the app always changes for to fro ie; form to from, formatting to fromatting, and so on. It’s not a huge deal just really annoying and distracting. It could also be a setting in my machine but I did not change anything and wouldn’t know where to start.

Thanks

It will also turn will to willl

Assuming when you say “always” it’s indeed each and every time that it happens. This is not standard behaviour.
Check whether you haven’t played around in Substitutions (File > Options > Corrections > Edit Substitutions) and inadvertently left something behind you shouldn’t have. If you have, remove the deviant substitution.

also look at autocompletion under Corrections Pane >Corrections and if on try turning it off and see if the problem persists.
