I see the same thing. And, when the roll is done the tape is useless to secure the finished roll. It doesn't stick. I use a rubber band to keep the roll wrapped tight, and then put it in a black plastid can for safe keeping until ready to develop, so it doesn't get light leaks.
It seems like nice film, though. But, I do make an effort to keep it rolled up tight while handling it so I don't get light leaks.
Don't lick the end tape. Peel off the little strips of pale yellow backing paper to reveal adhesive.
