WP Advanced Custom Fields data after import

I imported Custom Fields into my WordPress site from my staging server. Certain pages are no longer working.

I've tracked this down to a data issue. I went into the database and removed all entries from the wp_postmeta table that I am referencing on my page that is failing. I then went back into a post that was not working and did an update. That post now works.

This isn't a realistic approach since there are hundreds of posts that I would have to manually update. Any ideas on what I can do?
