Missing Ball Bearings in Leg Assembly?

I’m starting to build the legs according to the assembly instructions. The kit includes 4 BB. In step 1 and 4 we need to attached 2 per Leg (in total 4 for the leg pair kit). But in step 10 there is an extra BB illustrated and if I don’t include it then the screw would have some play with the rear panel of the tibia in step 14. The kit is supposed to bring all necessary pat to build the robot, so where can I find the BBs?

The ball bearings used to connect the legs to the body are included with the body kits themselves as opposed to the leg kits.

Hope this helps.

Thanks! I forgot to mention that it was the A-Pod. Then I have to hurry to the body kit.
