The previous entered results didn't come back during updating

I have completed my TurboTax 2023 entries and doing final review.  When I check my IRA entries with updating, I found the results come back not always the same as what I entered previously.  In particular, some IRA distributions are MRD but the results come back showing as non-RMD and vis versa.  After I correct that and save the return, however, when I did update again, the selected results became wrong again.  Is this normal?  I just don't want TurboTax kept the wrong entry.  Did anyone else have the same observation?  Please let me know.  Thanks!
