I was initially excited by that because I’ve had the misfortune of being given documents where someone basically did an “apply all” with Grammarly, which introduced a large number of significant errors. The author wasn’t a native speaker and assumed they hadn’t learned all of the rules correctly and made the mistake of trusting the tool.

It must have added unexpected work on your shoulders. Errors are definitely much better than wrong fixes. Good luck with your future work.
