So I've used this film in other backs no problems. Now, with my first run, I'm having quite a bit of problems. When I pull the first BLACK tab it breaks off and no white tab. Then I open up the back, of course exposing the first picture, to notice that TAB number 1 is in the back whereas I thought it would be in the front where the exposure window is???? I'm really confused as I did try pulling out the back tab, I'm assuming it's tab 10 and it's a beast to pull on. Any help please???? Thank you.
