Decimal trouble with PID settings

Hi,
I can’t use decimal with pid settings in antenna tracker. I would like to execute a fine tuning , but It’s impossible, because mission planner doesn’t permit to put the correct value.
I’searched on the forum, but I cannot found an answer. It’s only my problem?
Mission planner : last release
ArduTracker : last firmware
Thanks in advance for the answer, and fly safe! :blush:
Sorry for my english

How do you mean does not allow? With ranges you can usually just click through and do it anyway. Are you changing the param in the full list or tree?
