Pathauto Automated Alias not working properly when Content Types share a CCK field.

Forgive me if this is already posted, but I did not see it.

1) Drupal 6.22, Pathauto 6.x-1.3, Feeds 6.x-1.0-beta2

2) Create 2 Content Types (let's say "TypeA", "TypeB")

3) The two content types share a CCK field ("Original Article") ... which happens to be a url link to the original url of the individual item included in the feed

4) Items of this content type will be created via two separate RSS Feeds via Feeds Module

5) In Pathauto "node path settings," set:
"Pattern for all TypeA paths:"
typea/[title-raw]
"Pattern for all TypeB paths:"
typeb/[title-raw]

6) Result: Both TypeA and TypeB paths are being created as follows:
typeb/[title-raw]

I have tested this extensively playing with both settings and it has been consistent in this way.

Thanks for any guidance.
