Endpoint ID is "encoded" in inventory

Hi.
We notice that any endpoint ID code is actually not the real one but "encoded" and has any couple of character inverted.

If the real endpoint id is somethin live: 123456-7890...
in the inventory the enpoint is: 214365-8709

Thath could be a problem because if i want to use these id to isolate the machine, sophos api goes into and error for id not found
