As Lisa had no kids from her first marriage, it is very strange. Surely in her situation you would cut all ties, rather than trying to maintain a relationship for the sake of the children. In the real world, Zak would find it insane.
Belle must call her Granny as I imagine with Zak and Lisa being older parents, she never met any of her actual grandparents. Again, I'd find it more likely if Belle had a half-sibling who was actually Granny Clegg's grandchild. It's a very different thing to seeing a parent of a step parent as a grandparent.
