Tactical Codes

[=FI=Genosse]

Since the update 5.002 tactical codes/numbers have been introduced to IL-2 GB. On multiplayer servers my game seems to remember the tactical codes I had used before and sometimes it doesn't. I isolated my problem down to the following aircraft using the RAF codes:
 

• Spitfire Mk. XIV
• Spitfire Mk. XIVe
• P-38J-25
• P-51D-15

Is this a bug?
