parkour sign wont work in the new skyblock

I cant claim my parkour reward on skyblock

There is a barrier block above it, you sure that you're clicking on the sign and not the barrier block? Also, you can only do this once in 24 hours

that was my fist time doing it but I did it later on the other server

Try putting your microwave in a microwave in a microwave and than turn it on for 1min, that should fix it!
