This would happen if each of the wall tiles was of a different material.
It would also happen if the pawn was damaged so much that their carrying capacity was less than 10, so they could only carry materials for 1 tile at a time.
But I think you would realise if any of these were the reason, so this is prob something else. Could you provide a screenshot / savegame?
Can you repeat it over and over with the same pawn? With every pawn in the same game? Etc. Provide some more info plz.
