Session option is not displaying

Hello,

We have setup this plugin on the website and configure plugin related settings and enabled the “GeoIP rules”.
We have checked at front end but, currency is not converting on any Woocomemrce product pages like shop, product detail, cart and checkout.

We are using a “Light Speed” cache plugin on the website so, we have tried to change “Currency storage” options value, but “Currency storage” drop down is not displaying the “Session” option.

Kindly provide relevant solution for this.
