Images added to variation are out of order on website

[Horsefeathers]

Two issues with images at the variation level.

1. I've added two images, one is marked as "Primary". For some variations, the second image shows up first. I' ve tried multiple ways to resolve this, including deleting the item and all associated variations, but it keeps recurring.

2.  Even after deleting all the images from Square for Retail, they still persist on the website. I've done the usual troubleshooting (restart browser, Control-F5 refresh) and the images are still on the website even though they are not in Square.
