Video does not display and field is empty after save.

Hello, I recently installed/enabled Embedded Media Field, along with Embedded Video Field.

I set my proper user permissions for this module. In my content type (Blog), I have added a new field called "field_video" with a Type of "Embedded Video". Under Display fields, I left the Teaser and Full mode to both be Default.

I went in an created a new piece of content where I added a Vimeo embed code. I saved the content and received no errors. However, when I view the saved content, there is no video. When I go back in and edit the content, the URL/embed field is blank.

Attempting to use a YouTube (old embed code) video also yielded the same results. With the new embed code for YouTube, I received an error - as expected - which makes me think my issue is not related to my embed code. I have also attempted to change the "Display fields" to Full Video and some others, which does not seem to make a difference.

I have been unable to resolve this issue on my own and cannot seem to find any support tickets that mimic my problem. Does anyone have any solutions to try? I feel like it is something really obvious that I have forgotten to do.

I'm using Drupal 6, and this is taking place on a Drupal Commons 6.x-2.17 site. Similar modules such as ImageField and FileField were installed and configured and are working without issue.
