Some blueprints are being saved with massive empty margins/hologram (Megaprinters Mod)

See image attached. When saving this blueprint (made using the Megaprinters Mod), the blueprint is saved as a massive ?48x48 hologram, with the blueprint located right in the corner of this hologram. Other blueprints saved using this mod do not have the same behaviour. I've tried deleting & resaving the blueprint - nil change. Restarting the game also has no effect. Please help!
