Unstable basic land template not recognized as a basic land

I used the Unstable basic land template for my basic lands and when I generate a random pack it seeds them like regular cards, not basic lands. It also assigned a collector number like it's a regular card and not a basic land. Is there a workaround or fix for that?

Edit: I solved it. The issue is you can't choose the rarity for an Unstable land so you have to switch it to a normal M15 land, choose rarity as basic land, then switch it back to the Unstable land template.
