Maryland Schedule K -1 Error Message Section D Line 2

The PTE tax was recorded on federal schedule K-1, line 12 code S.  2 sharesholders 51%/49%.  The tax on respective shareholder's MD k-1's should populate correct?  Regardless, if I try to enter the amount on the 511 K-1 on the Maryland S corp return section D line 2 (total PTE tax paid)  I get an error message on the MD form 511 sch K-1 substitute the amount is incorrect - which apparently is why the return will not efile.  In turn this is creating an issue with the clients 1040 and 502 as well.  The amounts are correct, the S-Corp paid PTE tax for 51% shareholder of $510 the 49% shareholder $490.  The total on the Schedule K worksheet in the MD file should be on line 2 of section D as the total $1000, however, Proseries won't even let me enter $1000 on that line.  Not sure what I'm doing wrong.  A search of this issue hasn't turned up any similar issue with the form 511, however, I note there are still several issues with this form and the PTE reporting in general.
