Why is the parachute not inflating?

@CloakPin Thanks for answering me. I managed to solve this problem, but now a much worse one has appeared - and this time it's a real problem.

Continuous calibration until it works basically.
Once you get one to work youll be like “Oh ok thats how it works”!
But then youll notice the next parachute doesnt work with those settings so youll have to go through it all again each time.

Honestly there is a bit of consistency with them but not a whole lot.
