No option to do manual entry

Tailschwing:
Just got into a truck I’ve never driven before (32t FEL dustcart).

Was going to do a manual entry to show break but didn’t pop up with the usual prompt. Printout shows a ? for the period.

Does this mean it’ll show an infringement as thinks I haven’t had a break?

? Will be accepted as unaccounted time as you may have worked but not in transport.
Don’t worry
