Missing custom scenery from title sequence

[HarryLUFC]

Haven't been on the game in a while and came back and went on an old scenario, then noticed some of the title sequence parks have these 2 roof scenery types, I have some of the highlighted ones in my scenario currently by are missing the ones highlighted and the following 4, is there a way to find these?
I have added near enough all the custom scenery i have currently into my object selection in current scenario but these still arent appearing, but similar types are.

Thanks
