i have a 20% underdrive pulley with the matching belt but i noticed it doesnt have as many grooves as the other pulleys is that normal and since it doesnt have as many grooves will it cause my belt to slide or get shredded since all the pulleys dont match groove wise

It's normal. That underdrive pulley needs a 6 rib belt. It's one less rib than stock so align the belt so it matches the crank pulley on the rest.
