Other questions

I just updated to QB 2020 R14P. Now I see the issue as well. So, it's a new bug in R14.

It's quite the mystery, really, as when I downloaded R14 I got this message:

Maybe this is one of the issues "folks like you" (how condescending) asked to have fixed. You probably asked for a whole lot more white space when editing Inventory items. And Other Charges. And Subtotals. And Groups. And Discounts. And Sales Tax items.  But you liked the window as it was for sales tax groups, non inventory parts, and service items.

Or, more likely, Intuit didn't actually test the changes they made while they were "hard at work". Why test? What could go wrong?
