ERROR - GNSS Obersvation Node 'PointRecord' is Invalid

Trying to import a .jxl to TBC. The .jxl contains traverse data and scan data. Currently on TBC v5.52.

Things I've tried:

Installed TBC updates
Imported file to blank TBC project
Find/Replace ALL 'PointRecord' instances from file that DOES import
Turned on "all symbols" in Notepad++ and did a visual search for anomalies
Used the .job to create a "fresh" .jxl

I get the same error from the .job and .jxl. The PC included a .dc file which imports without issue but doesn't bring in the scan data.

Any help is appreciated! Thanks!
