Bug: Random RON increase

I have been experiencing a very furstating bug since the last update where the RON of the engine suddenly increases by about 5 units after selecting the manual test mode. This has happened multiple times and occurs without changing any engine parameters. I tune the engine perfectly to 95RON for example, works fine in the graph/data test mode, go to manual test and it knocks, then going back to the graph test mode it shows a large RON increase to around 97 to 100 RON.
Just thought i'd let you know. Happens on turbo and naturally aspirated.
