Hi, I'm really new to speedrunning and I have a problem that I don't know how to fix it. currently, I'm playing resident evil 3 (2020) remake and I have my time on any% new game(NG), but when I change it to new game+ (NG+) it still shows my time for NG so how can I reset the times for the game without losing it so I can go back to the runs I had and try improving it?

You want to make new splits all together, just changing the category in your splits won't work.

how do i do that?

Did you save those splits you made?If you didn't,do it.Name them however you want.Once you saved them,for NG+ you have to make entirely new splits.Once you make those NG+ splits,save them too.And now,when you want to switch splits on your live split,just press right click on open splits section and choose which ones you want to use.
