Cannot get static a/c to show marking in FMB

[timholt]

I have asked this a couple of times in previous posts but have yet to get an answer. I am sure earlier on I had static a/c showing markings in the first mission I built in FMB. I think there was a show markings tick box at one stage for static a/c. Can anyone verify this or am I losing the plot?
I have spent a considerable amount of time trying to figure this out to no avail.
It's probably going to be something ridiculously simple, but can someone tell me how please, or at least confirm it is not possible at this stage?
