Parameters don't work when in train station names.
Steps to reproduce.
1) Make a blueprint with a station with the [1] parameter in the station name, and an inserter with a [1] parameter as the filter.
2) Get BAD chest to deploy blueprint. The inserter will have the filter correctly set with the appropriate signal, but station name will still contain the parameter icon.
If you place the blueprint by hand, it will correctly set both parameters.
I hope this is an easy fix, its the last step in journey to make a station that can automatically request any train!
