Some backgrounds not working?

[Made Of Stone]

I have recently tried adding backgrounds to a custom database I am making, this database includes several new clubs within a new nation. To avoid UID problems I have overwritten extinct clubs rather than creating new ones; however when it has come to adding my backgrounds only some clubs seem to work properly and show on both match day and the info page. I have checked the config and that is completely fine and nothing seems wrong with the backgrounds themselves so I really do not know what is going on.

Has anyone experienced anything similar or know where I could be going wrong, it's driving me insane!
