Aelia currency switcher & Breeze cache problem

Hi,
lately your plugin is giving me compatibility problems with Aelia currency switcher. Basically, the product pages always show the currency in dollars even if I’m browsing from Italy and the currency in euros is selected. Aelia customer support said it’s a cache problem (which should be dynamic) and to contact you for help.
Unfortunately, I am very inexperienced and do not know if I have explained myself well.

Can you help me?

Thank you in advance for your help!
