I have 3 different pricelist all set to be selectable: 

1- public pricelist used as default

2-pricelist for Romania

3- pricelist for ukraine

When the client browse my website, by default odoo selects the pricelist based on his registration country and if it is unregistered user, it selects the public pricelist. but when the user tries to select from the dropdown list another pricelist to see in different currency, odoo doesn't set to the new pricelist and keeps showing the price in the automatically selected pricelist.

Is there any configuration to be done that I am missing?

Thank you for your help
