When I try to select PI Tags or do anything in the calculated data tab (or other data tabs for that matter) there is no response to my clicks or typing. The odd black boxes are there too, which are apparently not supposed to be there. I've searched the internet and discussed with more experienced individuals but I can't figure out what's going wrong. I have attached a picture of my screen to help show my issues. Again this screen doesn't do anything regardless of where I click. Any help is appreciated.
