We will need to see the scheme settings for the schedule.
I am guessing you have not used 'Element ID' for the field or you are not using the element ID on the windows (you may be using another parameter?).
The list system is very old and has not been kept up to date for some years.
New elements like stairs and rails can't be used in lists.
Although the old elements like windows and doors should still work.
It has been a long time since I have used list so I am not sure why they are not showing the window dimensions.
