Hello Christian:
This was a Processor Expert bug (check this).
The bug was fixed with PEx 10.4 Update 1 (10.4.1), but there is now an Update 2 (10.4.2), so I recommend you to install the latest so you have PEx 10.4.2.
For more details and installation instructions please check the next document in the community:
Processor Expert Driver Suite Update 10.4.2 available!
Regards!,
Jorge Gonzalez
