get_permalink() function not returning permalink displayed in post creation

I have a custom post type that has successfully been using pretty permalinks for a while now. However, after this last update some of my new posts no longer display the correct permalink when I call the get_permalink() function. If I go into the post editor, I see that the correct permalink is there such as http://www.site.com/events/full-event-name. But the get_permalink() function returns a http://www.site.com/?post_type=events&p=34478. I have been looking all over for why this is happening. I’ve tried deleting the posts and adding them back, adding rewrite flushes all over but every time the new posts end up with the bad permalink. What’s more, since the bad permalink isn’t accurate, no one can now use those links
