Liquid fuel doesn't register as a resource [USI (maybe)]

[OutlawFarmer]

I have a lot of mods that are mainly based around the USI family but a lot of others, my base is connected via the flex-o-tubes and I think thats part of the problem.

I installed a new refinery for LFO to make some T credits and when I fired up the processing unit it told me "liquid fuel full!", even though I had a rover with an empty LFO tank (the caribou VTOL), I even tried inflating a brand new empty storage module configured for Ore -> LFO.

I then tried making T credits in the logistics module with the little fuel I did have around and it told me "missing LiquidFuel".

when I tried to fire up the VTOL engines as a test, it didn't work with the fuel in the MKS inflatable storage but it did fire with the fuel in the tank.

I should also note that this is only happening with liquid fuel (and maybe the oxidizer too, but it probably first checks for liquid fuel and tells me about it), all other resources are transferring from storage to workshop to refinery to dill to w/e just fine.

google only shows people not knowing to put O in with the LFO and wonder why their rockets aren't taking off, anybody know whats up? am i missing something?
