ACF group looper true/false items

Hi,

ALLREADY SOLVED! For some reason ACF groups is the problem, now I use Tabs and okay!

I have an ACF fieldgroup with true/false items. Like a group Kitchen_comfort and in that group Fridge true/false, coffee maker true/false and so on. How can I loop these items in my Single layout and show only the true items?

And for my true/false options are not saving. If in Accomodaties tab Voorzieningen I put some fields to true, than I save and they are false again. I tried to disable all other plugins but still nog saving…
