sales tax is now negative when i try to pay it.

After changing the date ( back dated one month )  and value ( value for start of the prior month ) of my opening balance equity account, and then entering all sales, deposits, checks, charges, and ACH, my sales tax due in the Vendors..Sales Tax ... Pay Sales Tax window shows negative. I had to adjust the sales tax increasing it by a significant sum.  this feels like a bug as the reports for sales tax due all show positive correct values.

i am running the most recent release Quickbooks Desktop Pro Plus 2022
