Only Overlay output is the minimOSD version

[monkfood]

Sorry for open an issue for this, I was unable to find any description on the problem I am facing.
However I expect it is a typical behaviour. So the issue is more for an explanation in the WIKI

Issue details

Form one day to the other there is no telemetry overlay anymore but only the version without any suggestion of the problem.
The output shows: MinimOSD-Extra 2.4 Copter R682

What does this mean, what is to be done here. Where in the WIKI can I find an explanation.
Thank you. спаси́бо

Version

Board type
