Can't update custom user info / meta key?

I manage a blog that has about 30 writers. In our custom theme, we have a field for the writer to post their Facebook link. In one of the cases, the writer has updated his facebook_profile in his Profile area, and the database seems to be updated too, but it still shows the wrong link in the front.

I do have W3TC and “DB Cache Reloaded Fix” plugins, but I’ve cleared them both without any luck. Disabling those plugins didn’t seem to work either.

Here’s his profile area:

Here’s the database:

And here’s where the info is wrong: https://fstoppers.com/author/nick-f (it apparently takes you to his old link at https://www.facebook.com/shutterthink)

Please tell me what I’m doing wrong, and how I can fix this.

Thank you!
