“Update rate automatically” function

Hello, VillaTheme team
I need help
I enabled the “Update rate automatically” function(see attachment, image file name:3) but I found that all the imported products did not follow the price rule that I set.

for example,
I have imported the below Aliexpress product: https://www.aliexpress.com/item/1005002745056029.html

and here is the product link after imported: https://www.ueeplaza.com/product/custom-name-silicone-case-for-airpods-2/

according to the price rule that i set, let us take the color variation of RBEI001160355S for example, its Aliexpress price is $3.33, then the imported regular price should be $3.33*2=6.66, and change to euro should be $6.66*0.95=€6.33. but you can open the product link after imported: https://www.ueeplaza.com/product/custom-name-silicone-case-for-airpods-2/, the regular price shows €6.52, not €6.33.

why did this happen?

waiting for your urgent reply.
