Price not updated correctly

I have had the woocommerce shop for about 2 years for now. I have over 8000 products and i am updating the prices from csv on bulk. (Sadly company erp has no REST API). I have used both Woocommerce Import and WP all import but i dont think it makes a difference in my problem since i believe the root problem to be in woocommerce itself. This is what i am facing.

Example product “Shirt”:
Price showing in backend product search: 7,00 (old price)
Price showing when opening the product: 8,50 (new price)
Price showing in frontend shop: 7,00 (old price)

First i though it is an import issue. But i dont think it is since the price is actually imported correctly to the product. I have tested it many times and it does show a new price when i open the product. However it is just not updated to otherplaces for whatever reason. Also if i update it by hand say to 8,0 and then back to 8,5 it is updated correctly both to backend product search and frontend search/shop. This has been confusing me for a while and since it did not matter for few products now that i have hundreds with changes it is impossible to update them by hand.

Additional details: using storefront with child theme, caching plugins (obviously have reset cache) and couple other which should in no way interfere with product price. I also have tried to disable all plugins and reimport the csv but it did not help. I had an idea in mind that maybe there is a line of code or plugin that can check if the price in other places is same that it is in the actual product when it is opened.

Anyone else stumbled on such a matter or have any insight what could be the cause of this?
