There is no problem, I just find it unusual. But it is a very comfortable situation. Everything was done right at that point.
On the other hand, my savings bank advisor once said that only the first - in a specific case about 525m2 or so - can be valued at the full standard land value, as the rear part is not buildable. It would be different if you could put two houses on the area. As in your case actually.
But here we are drifting again into process details of individual banks. No idea if that helps further. But the bottom line is: area * standard land value does not always add up.
