This is correct.
Reported it to support and Simon replied with the same info, if the Encoder are registering a minimal turn when using the “push” function the [X] boxes will not register the push, due to overly sensitive encoder resolution.
Since i got this info i really try to push the knobs as centered as possible, which has improved my success rate by 95% i would say 
Still, should get improved since it feels dodgy when beeing unaware of the issue.
