Could you elaborate on how you couldnt use the blueprint?

Yes:
I picked up the blueprint, then I opened the fuel menu, I clicked on the blueprint, and there was another ui menu with 3 papers and 3 rocks, I tried to press them, but when my mouse exited the fuel menu it closed and I couldn't use the blueprint, because when the fuel menu closed, the blueprint's menu closed too;
