XF 2.0 Problem converting Youtube links to media bbcode

[The Dawg]

I imported VB 4.x to Xenforo 2 - Which went fine. I installed the Post Content / Find Replace tool to fix some of the Youtube links.

I ran query with the save box checked, it found 50+ instances. However, the posts were not changed. Should the posts display the new version automatically or do I rebuild all the posts?

If I need to rebuild the posts, how do I accomplish this?

Thanks.
