[Plugin: SEO Yoast] Part of company name missing in title

I used to use SEO Ultimate but changed a while ago to Yoast’s SEO plugin. Since then, our name hasn’t been appearing correctly in SERPS.

It should say Youth Workin’ It but instead only shows as Youth Workin. I’m assuming that the apostrophe is causing the name to be cut off, but is there any way to fix this? It’s not being caused due to having titles that are too long as it occurs on both short and long titles.
