twrp works fine but won't start via vol+power

Hi, as the title says, i can't boot to twrp when the phone is powered off. It will ignore what i push and just boot into cyanogenmod.
It used to work at some point, also i can get to twrp if i restart via the twrp app.

I should probably just reflash it?
If I'd somehow lock me from the os while experimenting, i could still run twrp via fastboot in ?

kind regards!
