lately I think I have lost the lack of clarity I had left, I can no longer solve simple things on my own.
today betaflight no longer saves me pid completely,
I usually use sliders, and I always find them as I had left them after each save, lately BF does strange things
I have tried on 3 different FCs. I have not made BF updates.
watch the video 

have patience with me 

maybe I'm not completely stoned,
this night in a dream I got enlightened.  

the only change I had made to all quads was to change the smoothed channels into 'rc smoothing'.
if I put RPYT RPY the sliders always work,
if I choose RPT RP T the sliders disappear.
practically disappear if I take off Y.

I don't know if it's a bug or it's intentional.

sometimes i have to wait up to a minute to save profiles... i think there is a bug between my hardware and software, if you wait longer for „refresh“ after „save“ does this help? the reason smoothed chnnels sounds funny xD nice if this solve it xD
otherwise github would be the place to find a reason or place an issue https://github.com/betaflight/betaflight/issues
