x-litespeed-cache: miss

Hi,
I have your CURCY – WooCommerce Multi Currency Premium plugin.
I have been trying to fix
https://check.lscache.io/?host=https://www.copperreflections.com/

x-litespeed-cache: miss
and
x-qc-cache: miss
all day. Finally, figure out that the problem is coming from your plugin: when I deactivate it, it is a hit for both.

Would you please help me solve this problem?

Thank you,

Tony Hisir
