Processing aberration or Light Seal issue?

Light seal issue or a processing aberration?

I shot a full roll of Fuji Superia 200 36 exp through my Canon AE-1 and these two and possibly another had this effect, so 2(3) out of 37 exposures. First time use of the AE-1.

The light seals look ok to my eye, but may pay to have a CLA done. Just seems unusual to have two images with this issue and the rest are prefect, though I did use a different lense after these two below were taken.

Thoughts please.

The two shots from the roll.

Random shot from the roll with different lens from the two above. No issues, happy with this.

My guess is light seals.

Reason that only two frames show it may be because of the time between frames, brightness of the ambient, position of camera, position of the sun, etc. Light seals are cheap. Change them out and enjoy the camera without wasting film.
