I've shared my avionics language and I keep it constant to reproduce that.
The only thing I change is Special -> mig-29a -> Customized cockpit.
When 'Customized cockpit' value is 'default(medium)' or 'default(low)' - I get this language discrepancy highlighted above.
When 'Customized cockpit' value is 'default' - I don't get this language discrepancy.
It is a minor issue - and I think it only affect those who need to play with native plane language and lower cockpit resolutions, like me - with pretty outdated PC.
Thank you!
