Site Builder Pagemap not working?

[Replicant]

It's nice to have Sitebuilder working again, however, I noticed the Page Map is no longer working (Blank textbox). It was working in 5.1.3 on my system. Just wondering if it is known to not be working on 5.1.4pl2 or if it's something on my system causing it. Using a VB default style. Only major change since upgrade from 5.1.3 is updated to PHP 5.5 from 5.3.

The page map will be removed in vB 5.1.5 (VBV-13508).
