Incorrect price shown

Hi, when I install Woocommerce Multi Currency, the default price appears sometimes modified. Example : I set the default price at 35.00$ CAD in Woocommerce, but the default price is displayed at 35.25$ CAD (or other amounts sometimes higher) when I load the website. When I switch to another currency and switch back to CAD currency by using the switcher, the default price is displayed correctly to 35.00$.
I suspect it as something to do with the caching plugin WP Rocket that I’m using. Any ideas how to solve this ?
Thank you,
