What problem? How do you solve? ???
Lol no one answered it so I figured it out elsewhere. I wasn't satisfied with the adhesion of my mortar. I am solving the problem by fulling grouting all of the cells, and possibly applying surface bonding cement afterwards. I'm required to grout my CMU anyway since it is 6 inch.
FWIW I think I was just ignorant about the properties of mortar. I examined another wall built by someone else and it had pretty similar properties, I guess I was thinking a block wall magically was strong before it's grouted. It seems without any other reinforcement block walls aren't good for much except in compression.
