Old urls are not being trapped by the standard Joomla 2.5 Redirect Manager

Having had problems with sh404sef it has been disabled and removed from my Joomla system. This has changed url behavior and I'm using the built in Redirect Manager to do this translation, after purging it completely of old entries.

Redirect Manager seems to be working properly for the main part of the Joomla site. It's trapping incoming urls and when I enter the corrected urls, it successfully traps and redirects to the correct page.

However bad urls that target the EasyBlog part of the site merely land on the front page. These bad urls do not get recorded as 404s in the Redirect Manager, and if I enter an expired and a new url pair in the re director it has no effect.

It's like something is trapping the bad EasyBlog url before it can get to the redirector. I've looked for any old sf404sef modules in EasyBlog, but haven't located any.

Here are some old and new url pairs for example purposes:

old: http://witchesandpagans.com/EasyBlog/how-i-met-and-was-blessed-by-belenus-on-beltane.html
new: http://witchesandpagans.com/pagan-paths-blogs/one-eyed-cat/how-i-met-belenus-on-beltane.html

old: http://www.witchesandpagans.com/One-Eyed-Cat/Blogger/Listings/shirl-sazynski.html
new: http://witchesandpagans.com/pagan-paths-blogs/one-eyed-cat/

The following one actually works correctly, even tho it has no entry in the redirector:

old: http://www.witchesandpagans.com/Pagan-Paths-Blogs/what-odin-taught-me-about-connection.html
new: http://www.witchesandpagans.com/pagan-paths-blogs/one-eyed-cat/what-odin-taught-me-about-connection.html

Any ideas?
