I am using the ATLauncher to play flowstates modpack and i have gotten back into it again but i have noticed that levelz isn't restricting my skills as I thought it would. It allows me to mine stone and upgrade to stone tools as soon as I get wood. Within minutes I have iron tools and I shouldn't be able to gain that and I shouldn't be able to. I wanna use the mod as intended and I don't know how to fix it. Does someone know how to fix this?

Version is 1.20.1
