Not letting me post

I've been trying to post classifieds. For some reason, the "Terms ( Categories / Tags ) (required)" isn't working properly (I select one, and then it's automatically deselected shortly after.

Ideally I have a title, description, duration, image, and related tags for the posting.

Note: Let me sum up, I want to create a buddypress network of job seekers and managers. I'd like to have auto-recommendations to both users based on profile information (job experience, location, etc.). Ideally managers will be able to post openings and people will be able to apply directly to them (with one click). If you have any recommendations for me, I'd appreciate it.

Thank you.
