Default [Help] Can't add widgets on sense 6

So i just updated my one m7 to sense 6 and decided to try out the original launcher (i have been using apex for a long time). But when i tried to add a widget to my homescreen through the option, it went back to my homescreen. Tried it with pinching the screen and it goes back to my homescreen immediately. i didnt press the back button but it keeps on doing it. Can somebody help?
