I am trying to follow this tutorial: https://youtu.be/CRSm-dNOogE
Slight problem however... It only selects one ico sphere at a time and applies the material to that one mesh. When I try to deselect it only get rid of the highlight. It still remains in the properties. I am clearly doing something wrong. Here's a screenshot that partially explains it.
