I have created new products, from duplicating from the original ones, which has always worked and has been fine.
Yesterday, I created the new product and it started to not aligned. I have found that if I manually put the newly created as the first product to display, all product after would be misaligned.
Welcome to the Shopify Community, and thanks for posting your question.
To confirm, the products on page Collections/Gift are not aligned? When viewing on my end, the product Sample Pack Espresso Series and Sample Pack
Milk Blend Series seem to have smaller images next to them.
Could you advise if you recently applied code to your theme or installed any new apps?
