The DM made a good catch on this spell.

If a walled keep were to be made in a DnD world, they would take in consideration the problems that magic causes and build accordingly.
Yes, they do take these spells into account. Separate blocks are just one way of doing this. Layered walls are also good for dealing with disintagrate attempts.

Limiting the spell is the wrong direction to cure the problem, for you hamstring the spell in other situations. You will have to be come a geologist just to figure out if you can use the spell or not. Does this block of granite have feldspar in it and if it does, it count as continuous because of it?
If you want to limit the spell in such a manner, that’s your choice. Stone types changing would not change it being one piece of stone.
if thats your call i would have used it on the morter and bought down a much larger chunk of the wall
Mortar is more glue than stone. IF the spell does work on most motars in the setting, then builders avoid using it.

You can form an existing piece of stone into any shape that suits your purpose. While it’s possible to make crude coffers, doors, and so forth with stone shape, fine detail isn’t possible. There is a 30% chance that any shape including moving parts simply doesn’t work.
Arcane Material Component
Soft clay, which must be worked into roughly the desired shape of the stone object and then touched to the stone while the verbal component is uttered.
