Do you have the same issue if you follow the OP’s steps to reproduce it?
Provide extra information to complete the original description of the issue:
I’ve tracked down the problem to the flap level definitions in the cockpit.cfg file. If the section is updated as follows the flap degrees in the HUD displays match the levels set by the flaps lever and the keyboard increment/decrement shortcuts:
[FLAPS_LEVELS]
flaps_level_1 =0
flaps_level_2 =5
flaps_level_3 =10
flaps_level_4 =15
flaps_level_5 =20
flaps_level_6 =25
flaps_level_7 =30
flaps_level_8 =35
flaps_level_9 =40
flaps_level_10 =45
