Having issues with my woocommerce website.

Hi , i don’t know if im in the right topic but i own a woocommerce dropshipping webshop.
After adding a couple of variable products i finally was ready to open my webshop. But unfortunately i couldn’t start yet. I had a problem with my products on my website. After a while they reset the price automaticly even tho i didn’t do anything! Like for instance a product which imported from aliexpress costs 5 dollar. I try to set the product price to 20 dollars but after two days it resets the price automaticly back to 5 dollars ?
How do you turn this off so it doesn’t reset the price after two days ???

I don’t know what im doing wrong maybe someone could might help me out ?

Thank you
