Apologies for the delay in my reply! I’m not receiving notifications to replies.

The second drop down is being caused by the theme. It is enhancing drop down too … all drop drown and not just ones created by the theme.

The only option is to hide it using CSS:

.cn-metabox-inside .dk_container {
    display:   none;
}

Unless, there is an option in the theme to disable enhancing the select drop downs.

That should fix it, please let me know if it does not.
