Amending Tax Return Not Working

I'm trying to amend my 2022 tax return.

 

Column A is supposed to be set and column B and C are the ones that you can make changes.

 

For the software,  Column C is set without allowing us to make any changes. Meanwhile, you can only make changes to Column A, with Column B making the +/- differences.

 

This is wrong. Update the software and fix the bug. Thanks.
