Deductions & credits

Seems like this is an on-going error for the 2021 tax year again.  Now Jan 27, 2022 with latest/today's update to TT Windows desktop deluxe.

It changes the MFJ $600 charitable contribution back to $300 and subsequently gives an error as "unacceptable value".  I manually change it to $600 in line 12b to correct it, and the software again changes back to $300 and throw the error again.  Standard Deduction, MFJ.  Stuck in a loop unfortunately.  And there was a similar issue last year based on what I read here.  Here is the screenshot.

There is only one "workaround": To delete ALL of my charitable contributions.  I know from the Tax Return perspective it does not matter, but I prefer to have it included just for annual comparisons and worksheet record keeping.
