Garmin data export → Athletica import creating a bunch of extra "Other" activities

Just as the title says, when I go to import my garmin history of fit files, the import pulls in a bunch of “other” files with durations between a few minutes to 15 hours. These files don’t seem to have much content other than time duration.

File view for reference

If you go back and look at the sessions, are they something odd / unique that doesn’t match with a label? Or are there other files in with the fit files?

If not, looks like a bug so best is probably to email the info and sceenshots and device info etc. to support@athletica.ai if so
