Adobe rejecting images for quality when there’s no evidence

I get rather frustrated when some of my stock photography is rejected for quality when others, taken in the studio at the same time, are accepted. I think that what is happening is that I am shooting close-ups, with a shallow depth of field. This depth of field is probably getting flagged automatically. Other images that have been accepted are the same depth of field with text in the image showing very clearly. So while the images are not identical, they are merely from different angles. Despite the fact that the ones accepted are actually getting purchased, it seems rather odd to have ones not accepted for quality when those that are accepted seem to be my most popular.
