A/A Radar: OSB label issues

In my latest A/G mission after a while

• the label for OSB19 (setting the azimuth 20/40/60/80/140°) for the A/A Radar got lost. Clicking the unlabelled button worked (azimuth setting changed) as intended.
  
• OSB05 was labelled wrong and showed "MAP" instead "RWS" or "TWS"
  

Both issues occured while A/G Master Mode was active. After switching to A/A Master mode by selecting an A/A weapon the correct labels returned. I think, the described behaviour in that post is also related to this issue.

See attached screenshot. The original mission track was too large (> 25 MB), but I could reproduce* the issue, see attached trackfile.

1. set A/G Master Mode (activates A/G Radar @R-DDI)
   
2. select A/A Radar
   
3. switch to another page (i. e. SA) @R-DDI)
   
4. switch back to Radar @R-DDI
   
5. label issues

I can confirm that the label for OSB19 (setting the azimuth 20/40/60/80/140°) for the A/A Radar is still not showing, when slewing cursor over. Clicking empty fields changes the azimuth degrees though. Picture is attached. Using latest OpenBeta.
