Reverse Charged Tax Code - Tax Summary vs Tax Transactions Report

For example, before version 20.8.65, my tax summary report for June-2020 would show my sales/purchases and taxes as below

but when I pull the same report after the update of 20.8.65 the report shows as below which is not correct and the same happens for all previous months.

In January-2020, I had a transaction report saved which showed totals as below

but when I pull the same report after update, I get these totals which are incorrect

I just don’t understand why the sales/purchase and tax figures have suddenly changed with this new update.
