Converting Wrong Prices when change currency.

The Default currency is USD and price for a product (variation – variable product) is $200. Everything works fine til currency is not changed. When the currency is changed to some other say GBP it doesn’t convert according to the rate we have entered in the settings.

Attachment 1: Rates entered
Attachment 2: Price when the selected currency is USD (200)
Attachment 3: Price when any other currency is selected – in Screenshot, GBP is selected: the conversion rate is 0.756 so the price should be
200*0.756 = 151 but as you can see in the screenshot it’s 131.

Please, advice. Thanks.
