APRS full feeds is full of invalid messages, so it is not unusual to see parse errors. It possible that some of them are bugs in library, that needs to be addressed, generally it good smell test is to check if https://aprs.fi has successfully decoded the message in question.

For format not support, simply adding support. That can be straightforward or complicated.
