Generative fill results show edges of selection area

Hello! I've been having issues with Photoshop's generative fill feature today. Every time I select an area to generative fill, the results are mismatched to the background and my selection area is visible (see below, above the generative toolbar). This same thing happens no matter how many times I regenerate and if I select a different area. It's happened on other photos I've tested as well.
