[DG] Realvision 3D sloping bottom problem

I have an Axiom 12 pro RVX connected to RV-212S and RV-212P (12deg) plus some other Raymarine kit recently fitted to a Botnia Targa 31.

The problem I have is that the bottom on Realvison 3D is not displayed as an constant depth but rather as a slope even when I know it to be flat.

Other than that the Realvison 3D seems to be working ok.

Is there some adjustment I need to do?

See attached screenshots of examples of the problem.
