Weird results when exporting reg file

[basilisk0315]

Hello,

I set my GPU to use IrqPolicySpecifiedProcessors and then exported the registry settings. This resulting reg file showed this:
"AssignmentSetOverride"=hex:c0,00

However, when I export the same registry key using regedit and Registry Finder, the resulting reg file showed this:
"AssignmentSetOverride"=hex:00,c0

We can see the hex values do not match.

Edit: in addition, for a different device GoInterruptPolicy exported this:
"AssignmentSetOverride"=hex:30,00,0
Note: the single 0.

While regedit exported this for the same:
"AssignmentSetOverride"=hex:00,00,03

Is this expected?

Cheers
John
