Barcode No cancel doesn't work

Hi all,

I have an issue with Barcode archiving. When I check the box "Cancel" in OAC5 I expect that the user can't cancel the Barcode Popup. But it doesn't work as I expected.

The user has the possibilty via X Button to cancel this Popup. See Screenshot this Button is active.

Customized is OAC0, OAC2, OAC3 and OAC5. Did I forgot something?
