MOX Waste not removed by trucks from Nuclear Reactor 2

Issue description

I have the Nuclear Reactor 2 running, on mixed load of normal and MOX fuel.
I use trucks to remove the waste. They happily remove the spent regular waste. But they dont want to remove the MOX waste, it basically gets ignored and no truck comes to pick it up.
So it accumulates in the reactor until no more MOX fuel can be used.

I have readioactive waste storages for both normal spent fuel and spent MOX fuel , both are fully operational, have correct import settings and everything (Keep Full, Import enabled)
The reactor and the radioactive storages are all at priority 2, Truck Logistic situation is stable.

Reproduction steps

Build Reactor 2
run it with both MOX and standard fuels
use trucks for removing the waste
watch how MOX waste is never picked up

Game version and build number

v0.5.5d (b260)

Operating system

Windows

Would you have a save file? I don't think this happens by default.

This save file is from .5.5, loaded in .6.2 again and saved to focus view on reactor and adjacent mox waste storage
moxFuel.save

Files not imported: moxFuel.save

I'm having this same issue. Interestingly, I've verified that trucks are able to carry both MOX fuel and spent MOX from their respective storage facilities to other storage facilities, but they won't either drop it off or pick it up directly from a Nuclear Reactor 2.

This was fixed in one of our recent updates. Thanks for reporting it!
