The price for the variable product does not change

I’m having a problem updating variable product prices.
My products have the same SKUs in one of the variations and the parent product.

And when I want to update the prices, in the Simple product mode, the price only changes for the parent product, the price for the variable product does not change…

Please help resolve this problem
