Auto Foundations under Railways built in blueprint designer not present in built blueprint

Context: I am on a creative world. In a blueprint designer (I've tested the vanilla designer as well as modded), I use the FUR mod by @Andre Aquila <Aquila Industrial> to build a nice curve. The foundations appear perfectly and seem to save correctly. When loaded via the blueprint designer, the auto-built foundations appear perfectly fine. The problem: When I build the blueprint outside the blueprint designer, the auto-built foundations do not appear. I understand from the mod description that it will not auto-build them from a blueprint, but I thought the foundations saved in the blueprint designer would be built. To illustrate, build a rail in a blueprint designer with the auto-spawning foundations. Delete the rail. The foundations are still present. Save the blueprint, and build it outside of the designer. The foundations are no longer present. As far as I understand, this isn't intended behavior? Or perhaps I've misunderstood the mod description. Either way, I'd like some help with what's going wrong here.

My best guess is that the foundations are spawned outside of the blueprint designers influence - not sure how practical it would be for @Andre Aquila <Aquila Industrial> to change that
