Filter/Session Issue

Hello all,
This may be a quick fix, something I am overlooking regarding sessions! 
I'm using Version 4.4.4.
I have a few filters: dashboard, admin, and developer.
Everything has been working fine and then suddenly I cannot access the developer area.
I have searched and found nothing addressing something similar to this. I can't figure it out.
When I dump the session variables in the developer filter the only item appearing is the '__ci_last_regenerate' entry, causing the filter to send me to the dashboard.
The dashboard and admin filter is working properly and when I dump the session variables, everything is there. When I look at the CI toolbar, everything is there too. The session data persists throughout the application just not in the developer filter.
I am not sure what I am overlooking. Any help will be much appreciated! Thank you!!
