You are right, they are more expensive then I thought.
Did you split the input? ( one solar array/ controller)
No, unless they are out of MPPT algorithm, and/or are in bulk/float. If you are entering bulk phase or float then it's normal I think, the battery can't except all energy the solar is producing. You can try to set them with each a little bit different settings.
If you did calibration right, a new calibration will not help, my first controller was put on the wall and I never did a new calibration.
I found these: still expensive and on the other side of the world for you
