[2.0.15] Blueprint parameters in train schedules aren't displayed correctly

[DeadMG]

What did you do?
I made a blueprint for a train stop. This blueprint includes a train that services it. I then parameterised this print.

What happened?
The parameterisation dialog shows where the parameter is used. This includes the train stop and combinators, but not the train schedule. The schedule is correctly parameterised, but it looks like it isn't.

What did you expect to happen instead? It might be obvious to you, but do it anyway!
The parameterisation dialog should display when the parameter impacts the train schedule.

Does it happen always, once, or sometimes?
Always.
