Don't worry about it - it is normal. If you look at the shutter area
of any 35mm camera, you will see rails at the top and bottom that hold
the film slightly above the surface the shutter opening is cut into.
This means that there is a slight gap between the film and frame mask
at the frame ends. A VERY bright (and/or VERY overexposed) subject at
the end of one frame will often spill light onto the next frame (and
it may also travel through the film itself).
Hope This Helps
