Re learn moves disappeared?

[JRW98]

I had to get a new pc as mine got stolen and I had to re download PKHex, when I did I noticed it had changed a lot since the 2021 version of PKHex I have been using. I’ve noticed on these newer versions that I can’t find the relearn moves section for egg moves? I’ve deleted the new version and downloaded the oldest version that I can which is March 1st 2022 (still newer than what I had before) and it’s still not there? How do I get re lane moves back?
