Infinite POWER

[jacksonflats]

Haha, catchy title. I built a ship using stock, porkjet atomic age and quiztech aerospace engines and now I have issues. Mechjeb says that I have infinity delta v while Kerbal engineer says that I have 0. This is for all engines, no matter which one I select it always says this. I have fuel and oxidizer left over in the tanks connect to the engines. Note, this problem only appeared once I entered orbit, so before the delta v calculations were fine. Any suggestions as to what to try?

Don't the porkjet atomic jet engines run forever? Could be those not playing nice.

One does (the atmosphere one), but I'm not using it. Instead, I have the "Lantern" which has 2 modes- LF high efficiency and LFO high thrust. Also, the engines still consume fuel so it's not true infinite power like MechJeb says

It could be that the two modes are messing with MJ's calculations
