Drag and drop

So i created simple drag and drop operation. Created Drag and drop object where i store variable that is passed between operations, item info. Everything works. When i close project and open it again drag and drop does not work. I have to go to drag detected bp and deselect created drag and drop object save it and than choose my created drag and drop object and boom everything works. What am i doing wrong. I tried everything i can and still it wont work. Any ideas?
