Polyscope X 10.12.1: Difference in program exported on USB to Robot API

Technical Questions
1

I just noticed, when I export my urpx programs, they are ways bigger than when exported on a USB disk.

I cannot share the files but assure they are the same program captured at the same time (the 2h difference just comes from different time zone handling on robot or so).

Anyone else noticed this? Do I need to be concerned?

Update, putting the API exported program on an usb disk, and importing it works. if you then export it to usb again it is 354KB again. the files then almost match, its just some id and naming stuff that changes.
