Court Houses

I am currently trying to photograph the interesting court houses in the UK.

BUT...

It's a lottery if they are accepted or not.

I have an image of the court building in Manchester that has sold twice in less than six months. 

Yesterday I uploaded photos of Liverpool court building and they were rejected in less than 12 hours.

I don't understand what the issue is, either accept them all or reject them all, not accept some and not others.

Does anyone else have this issue?

Can I ask Adobe to have a look and confirm their editorial policy?
