Getting Hebrew lemmas when I am asking for Greek

Can someone help me out here. I am building new Visual Filters for Greek lemmas. My filter is set for Greek morphology in a Greek text. I want to create a filter to mark every kai in the text (working on discourse grammar). When I type lemma:kai this list of words that it brings up are Hebrew. If I do this same thing in a Morph search the functionality is correct and I get a list of Greek words to choose from. What am I doing wrong here. I have done this hundreds of times before, but the functionality or syntax in Visual filters seems to have changed.
