Thread:Support/proofread, but the old one is still appearing on my home wiki

I read FAQ and it said that after changes are committed/proofread, they usually appear on my home wiki within 24 hours. Well, one man changed MediaWiki:Uctop/th 4 days ago. I proofread it and deleted that message in my home wiki (w:th:MediaWiki:Uctop) in that day as well. But now that message haven't come yet. What happened?

By the way, I have other questions too.
 * 1) I noticed that some messages can be proofread for multiple times. Is this the reason that caused message didn't come to my home wiki (because it needed more reviews)?
 * 2) Is there a way to find if particular message has been proofread?

Thank you :)
