Why is my staging tree all blank?

[vans0051]

Any idea why my staging would turn into this...?

 

Many mods, including MechJeb, Infernal Robotics, SpaceY & SpaceY Expanded, FinalFrontier, Modular Pods, Modular Rocket Systems, and Interstellar Fuel Switch.  This is a novel issue - I've never seen it before.  I think I've used everything without problems in the past, the only possible exception is Modular Pods - it's a rather new add-on for me.

Any ideas on the cause and possible fixes?

From the looks of it, you have just undocked from what appears to be a station.

Make sure that the craft you are in control off is the active craft.

Both craft had the same issue.

 

Thanks for trying.

it might help if we could see whats in the picture better, but I'm totally at a loss for this issue, in addition to all the stages being blank, it also appears that they are all stage 4.
