Default Small cracks in Refractory Mortar

Hoping for some advice. I have assembled a Casa 2G90 and after firing it I am starting to see small cracks in the mortar on the joints. Followed the firing instructions and I do not think that I went too hot too soon. My thoughts are that I did not get the mortar mixed to the right consistency when I applied it. One of the spots where the mortar is cracking also seems to move when you push on it like there is an air pocket underneath. I have read some posts and understand that some cracking is normal but I am still at a point where I could try to remove and apply more mortar if that is necessary. Any tips would be good. I have attached a couple of pics.
