When JoomSEF is enabled for k2, a module i have in my side bar has it's urls rewritten incorrectly. mod_k2_filter is using an extra field displayed as a list.

/education/itemlist/filter?searchword=Acid+Reflux -- without JoomSEF, which works
/education/filter?&searchword=Acid Reflux&task=filter -- with JoomSEF Basic, which does not work
/education/filter?&searchword=Acid%20Reflux&task=filter -- with JoomSEF, which does not work either

Im dont care how the urls look, but i do want to have the meta info attributed correctly; and for the url to resolve correctly. I cannot turn off the k2 extention, as the entire site uses k2 items, categories, and extra fields.

Is there some sort of setting that i am unaware of that can fix my issue?

Joomla 1.5.23
K2 2.4.1
JoomSEF 3.8.2
JoomSEF K2 extension 2.0.5
