Traceback error using `Level2File` opening a start L2 radar chunk file

What went wrong?

I get a traceback error when trying to opening the start file of a L2 chunk of a volume for specific radar towers: KJKL, KCCX, KMBX, KDDC, KTYX and potentially others too.

Most towers work fine and I'm not familiar enough with the msg formats to know why/how these sites are different.

Operating System

Linux

from metpy.io import Level2File
l2file = Level2File("20240227-102059-001-S")
