Autofill credit card info broken on some forms but not others

I have my credit card info correctly saved in the FF settings on my PC desktop, but it doesn't work correctly on some online forms.

When it fails to work I click on the truncated information for the saved credit card I wish to use, but it fills in later numbers in the sequence incorrectly with the wrong digits and too few numbers to even be a legitimate credit card number

I have double checked in the settings, "privacy and security", and the credit card numbers are entered correctly there and enabled.

The form I have most recently had issues with were for a local "big day of giving" site, and it is powered by something called "mighty cause."

I can't include a screenshot of the issue itself occurring or my settings, for obvious reasons.

My PC is windows 11 home edition, and the version of Firefox is 150.0.1 (I think).
