Admin search not working when plugin enabled

When I do a search in my posts (admin/backend Posts), no matter what I type, it comes up with “no posts found”. Was doing my head in trying to figure it out, searching, reading forums, and couldn’t find any solution until I disabled the Admin Taxonomy Filter plugin (which I only installed last night). The Search function is working again. Not sure what is going on there, but I use my search function every few hours, so it’s a shame that I won’t be able to use this plugin.
