Datepicker advertising on windows tab

Datepicker advertising on windows tab

I need help modifying some strange jQuery UI datepicker behavior. 

The datepicker is working perfectly as advertised inside my website, but has taken up advertising on my website windows tab. The name of my website has been replaced on the windows tab with "jQuery UI Datepicker - Default functionality".

Appreciate your help getting my website name back on the windows tab.
