Uploading TCX or FIT files

Please can anyone help with some advice on this?

For some years I have created routes on Ride with GPS and uploaded them to my Fenix 5 by dragging the downloaded file into the new files folder. Recently, this doesn’t work. The file appears in the folder when connected to the laptop but is not on the device under Navigate when disconnected. I’ve tried multiple times and switched between fit and tcx to no avail.

thanks in advance for any help….
