Current default for USB ethernet (AFAIK) is to use enxNNNNNNNNNNNN 
where the NNNNNNNNNNN is the MAC address. It might be that the fact that 
they're OTG that's confusing something, you might have an alternate 
configuration, or it could be an older version. If it is the current 
version on a clean install I'd simply consider it a bug.

The kernel increments the USB device number for each new device. If 
you're using the systemd option to name based on device path rather than 
MAC, it's inevitable that it will change on add/remove because systemd 
is getting the information from the kernel.
