Error in Shortcodes Generator

Hello.

I have a theme called PAX which has some built in shortcodes that can be selected from the html console within posts and pages ect.

When i select a shortcode to use it comes up with a popup page for me to select options for the shortcode and when i click on a dropdown ther are 2 selctions that are random code. 1 is as below.

ue="function (from, to) { var rest = this.slice((to || from) + 1 || this.length); this.length = from < 0 ? this.length + from : from; return this.push.apply(this, rest);}

Also there are 2 blank input fields.

Can anybody advise on what these are and how to solve the problem.

Thank You.
