landing flaps behavior

i have automatic flaps disabled but they still move (unwanted) if i lower the thrust, as example in a Learjet i get overspeed ..

Quote from Jet-Pack (IPACS)

Please check your control assignments for the flaps. Perhaps you accidentally have flaps assigned on the same axis or a button at the end of the thrust lever range (e.g. for button reverse gets triggered and is assigned to flaps somehow.)

ups, that was the case, thank you very much.
