Why are my multi-variant products redirecting to incorrect URLs?

Hello Recently I have been facing some issues with the redirection of my products, for some reason only the products that have more than 1 Variant, example Color and Size or Style and Model, are being affected by this, every time I try to view such products I am met with the correct page for a split second but immediately get redirected to a URL that is incorrect. Here are some example products and a video showcasing my issue:

Examples:

1- https://memoo.co.kr/collections/autumn-collection-i-%D9%85%D8%AC%D9%85%D9%88%D8%B9%D8%A9-%D8%A7%D9%84%D8%AE%D8%B1%D9%8A%D9%81/products/jeans-rivro-washing-wide-denim-pants

2- https://memoo.co.kr/products/one-iphone-11-pro-max-blackpink-phonecase

3- https://memoo.co.kr/products/jeans-damage-washing-cotton-pants

I have already tried checking out the products with other themes such as the one provided by shopify, “Debut” but found that I did not face this issue, I have deduced it is from the current theme I am using.

If someone could please help me with this, my skype is This, or please send me a message it would be much appreciated. Thank you.
