Clear Streak on Film Negative - Film Developing Issue

[christophaar]

I've been developing colour film with my Jobo ATL1000 and on the last roll I had a clear streak towards the start of the roll that went through the first frame. I had just mixed new chemistry, which was Tetenal Colortec C41. I haven't scanned it yet to find out how that last frame will look, as I normally have them scanned at a lab. But I'm curious to what could of caused this issue? Thanks in advance for any help!

The clear patch was in contact with the rear of the film below it on the spiral during development.
