[Plugin: Sermon Browser] unable to remove preachers

I added new preachers, but the preachers don’t show on the “add preachers” page and then when I try to delete the one preacher that’s there, it won’t let me. But when I go to add a sermon, the preachers are there in the list. I’ve also run into other bugs as well.
