2 Sites – 1 not displaying Newest First Problem

Hi guys.

Ok got a problem that is really annoying.

I have 2 sites running the exact same import system, theme and plugins.

Shop4more.co.uk displays products correctly in Newest order first
magicworldonline.com is displaying say the first 10 products correctly on a category then starts mixing in products from 2019 and 2018!

Please can someone help?

For eg compare:
https://www.magicworldonline.com/category/new/ To:
https://www.shop4more.co.uk/category/new-magic-tricks/

Or https://www.magicworldonline.com/category/playing-cards/ To
https://www.shop4more.co.uk/category/decks-custom-standard/

Both start okay but then after 7-8 products goes off on a tangent!

This is happening on all categories.

I have chosen the same settings in customizer / woocommerce to be Show by
“Sort by most recent”

Can anyone advise where I am going wrong? Please compare from about page 2-3 on each category and on magicworldonline suddenly my site is overwhelmed with download products and not mixing all the downloads and regular in the latest date released fashion!

Many thanks,
Anthony
