On my products, customers have 2 options to select. When option 1 is selected, all additional product images are shown, but when you select option 2, all the extra images vanish and there is just 1 stock image.

I have noticed in the Products section under the tab Sales > Extra Product Media, only about 10 out of 120 products have images and the rest are blank. The ones with the images are the products that don't vanish when selecting both options on the product page.

How can make sure the product images remain the same for both option 1 and option 2? 

Does it mean I have to spend many hours deleting and re-uploading all 1100 images under the Extra Product Media section instead of on the product page?

Odoo is extremely frustrating to work with and always seems to mess up. I am using odoo 16.
