Funky GPS with T-echo

I've got two T-echos, and they both always give the same static GPS coordinates, literally overlapping on the map even if they are a mile apart.

I hooked one up to mesh sense, and looked at the position config. It says gpsEndabled:false? In the iOS app UI it shows enabled.

What's even weirder, if I try to use the web client to configure position, the page gives an error: Cannot read properties of undefined (reading 'positionFlags')

Anyone have this issue? Any suggestions? I got them from Rokland, so my next step is to reach out to them in case the units are defective, but I thought I'd check here first.
