Is anyone else having issues with saved Custom Reports turning into Modern View if you edit anything in the report?

I have Custom Reports based on a P&L by Class. If I edit any of the income or expense items on the P&L, when I save the edited item, the report switches to Modern View. Modern View doesn't work for me for soooo many reasons. When I switch back to Class View, it messes up the Header/Footer and adds the Report Basis. If I click on the item I edited again, it stays at Classic View and most of the time the Report Basis is gone. I spent a lot of time screen sharing with Intuit but because she couldn't make her version do the same thing, they won't fix it. I have to edit almost 100 reports this month and this annoying glitch really slows me down. Just wondering if anyone else has experienced the same thing. Also, when I use a Custom Report and click to go back to the report list, now it takes me to Standard Reports instead of going back to Custom Reports.
