trenches in forts?

[Nordiska]

I noticed that I can't build trenches in a captured fort hex. For example as CP, I can't build a trench in a leige fort 0 hex but can build trenches up to level 2 in other hexs in France/Belgium. Is it supposed to be that way or is it a bug? Also if I try to build a trench there, I lose a trench point but the trench doesn't appear. Thanks

That doesn't sound right, I'll check it.

I think it might be a question of display - Liege doesn't show as having 2 trenches but infantry therein should have a "2" sign displayed showing they are in existence.

I am using the alternate graphics. I see what you mean on the counter they have listed they are entrenched but on the gray box on the bottom next to supply % it always has trench zero or the fort zero for the fort areas.
