If you are planning to efile the return, then un-check the "enable conversion error checking" box at the time you actually start to efile.  This was suggested on this site, and I was able to efile a MD return that contained these "errors," and it was accepted.  If you are using eSignature, the forms will not produce because of these errors, but you can sign directly into DocuSign, and manually upload whatever forms you want to the envelope.  I don't understand what is going on with the Maryland returns this year, but this is just one of several frustrations.  Heck, the MD Comptroller's website is not yet set up to be able to schedule 2022 estimated tax payments!
