Hi Torben,
If any of the conditional sensors to the logix are unknown, then it won't be able to calculate so worth checking the appearance in the Signal Mast Logic table,
then in sensor table for any sensors which the feather uses as input conditional.
For the flashing on / off whenever the mast is set to red, again would be worth having a look at the conditional logic,
especially which conditions trigger the change.
Although the method for creating a feather aspect has changed, the principles behind the conditional logic triggers are shown well in?
Nigel Cliffe's infamous JMRI signalling videos, note especially the use of logix:
Hope this helps,
Steve.
