I'm using a sample project to get to know Jira, but I'm having problems creating issues. I can only assign them to boards in a different project, not the project I'm trying to create the issue in.
I've also tried creating my own project in case that made a difference, but the same thing happened - I can only select from the two boards in our company's other project (blacked out in the image below).

I've looked around in board and project settings and haven't been able to find anything relevant. Would really appreciate any help on how to fix this - unless I've misunderstood how boards and projects work, in which case I'd be very grateful for an explanation
