I think my Shining Pearl is glitched and the flag for that I should visit the league won't disappear

I think my Shining Pearl is glitched.

After defeating the E4 for the first time, I decided to rematch the gym leaders (I've also been to the post-game island). After Volkner, I decided to talk to Jasmine and noticed she gave the TMs for waterfall (I guess I never got it from her before). Then I checked my map and it says I should go to the Pokemon league. After defeating it for the third time, it still shows on my map that I should go there. How do I fix this?

I imagine a flag or event constant controls what dialogue should be displayed below. Use a different save to find out what flag/constant it is, then apply the value to your original save.

Which flag under what tab should I be looking for on PKHeX?

Research allows you to load old and new save to compare. it'll show differences.
Best if the save is from directly before and after.
