This looks like when processing software called the NOIRLab Community Pipeline that misrecognized a lensed galaxy as a cosmic ray, which then trims it out.

The Single Image Exposures link gives me several i-band exposures that recognized the galaxy as a cosmic ray.

Show list of exposures that removes the galaxy
