Parsing 999 fails when TA1 exists

[Edwardiv1]

Parsing the following fails with the errors messages:
Error: ANSI version 000 not consistent with version specified ANSI837_5010_X231

999 Data file:

The problem is the TA1 line (second line), which says the file was accepted. Usually TA1 is only included if there's a rejection, but in this case the clearinghouse is including it even though the status is "A".
Looks like the parser is reading it expecting it to be the GS segment (?)
