[2.0.21] train stuck at refuelling station after changing fuel type

[R00bin800]

Wat did you do?
I just changed fuel types in my automatic fuel station from rocket fuel to nuclear fuel.
It uses an interrupt that has a target that all locomotives need to be fully fueled.

What happened?
The train gets 3 nuclear fuel, so it is fully fueled. It flashes the condition green, so it is fully fueled, and then not. See attached video

What did you expect to happen?
I expected the train to get fully fueled and then leave the station and resume it's normal schedule.

Does it happen always, once, or sometimes?
It happens with all my trains.

I assume your interrupt is broken and triggered again.
