The bouyantbuoyant force IS the contact force.
Forces are:-
For the block: Its own weight and the bouyantbuoyant force(or "contact force") by the liquid.
For the liquid: Its own weight, the contact force by block (equal and opposite to the bouyantbuoyant force by the liquid on the block) and the contact force by the beaker.
These are all if you consider liquid and block. I see you also got the direction of bouyantbuoyant force wrong too. It would actually be upwards on the block.
