New Counting System causing New Issues

I am Having big problems and I am hoping you can help. I have had PPC now for over 2 years and we pay our authors for page views monthly. A blog can continue earning until it reaches 1000 views. Some authors have over 800 blogs dating back to April 2021 that they still make a little money on. Here is my problem. I installed slimstat 3 months ago, so the data is only 3 months back. When I select slimstat as my counting method the authors earnings go negative if I select a date back to April 2021 or all time, I am guessing since it has no data to draw from its assuming I overpaid these people so I see a negative number. I do not allow them to see the history so I was thinking if I delete the payments then it can be corrected. The problem is when I set the stats to 2021 or all time the stats page is timing out, so I cant even try to resolve the problem. I cannot set the dates for shorter times since it reflects like the older blogs never even existed and will do that going forward I am assuming. O am open to suggestions to resolve this problem, especially the stats page timing out. It does not do that when I switch back to Google analytics as a counting option. I have also added plausible, but it only has one days data, so that method would have to wait. I am open to suggestions to resolve these problems. I have post Pay Counter, PPC Pro, Buddypress, User Roles, and Author Bonus. ?Thanks in advance.
