How do you delete missions
 

I have searched the website, forums and even Google and haven't found an answer on how you delete missions you aren't going to do that sit of to the right hand side of your screen under the mini map. There is a delete button in my log but it's grayed out and I can't delete them. So how do I get them off the mission list under the mini map?

I didnt have problems deleting missions. If I recall, it was from the episodes tab. But maybe yours is bugged?
