RC inputs still work in GUIDED!

I arm my quadcopter and then switch to GUIDED, however the RC input sticks, still work, and the drone can still increase its throttle through them, which makes it as if GUIDED is not enabled, however I checked that it is in fact enabled, in ArduPilot Mission Planner, but I am really surprised why GUIDED does not behave as expected. I would really appreciate your guidance to figure out this issue

It works as expected.
If you do not want the sticks to have an effect do not move them. They are a fallback in case you need to take manual control fast

Is there a better way to disable the sticks, sometimes they could be triggered by mistake like a sudden unintentional move, I would be really grateful to know how can disable only the sticks and keep the rest of the RC buttons working
