@ShanQureshi - i checked code there are some javascript issues, can you please take import font line out of script and put it in head part of the theme.liquid and then check again?

this may not be the exact solution but javascript errors often do not let button clicks work

@ShanQureshi - please open product page in customize settings and check if you have an option to disable pop up, if no then you need to contact theme developers as popup is default functionality.
