HL7 to SQLite with Mirth Connect

I'm trying to build a channel to read an HL7 ADT text file, extract an MRN and write output to a SQLite table (Database Writer).

My SQLite table contains my data but all my PatientIDs are appearing as a concatenated string in one very wide column. As opposed to a PatientID per row/record.

I'm noticing some weird illegal(?) characters in my HL7 file (which come from a Meditech EMR). In QuickViewHL7 they appear in the MSH-22 and MSH-30.

In the VIM editor -

My question is, are these supposed to be delimiters? If so, what are they? Carriage Returns?

I've posted this question on the Mirth Connect forums but seen little but tumbleweeds. I'm hoping someone here might have seen this before and tell me what's going on.
