Updates to dropdown form not appearing in preview or live website

I'm having issues with changes to one of the dropdown menus in my jotform. Any update I make is not showing up in either the preview or live website. Specifically I'm trying to add an option under the "Instrument" dropdown menu on the form.

I've seen this question asked countless times, with support just saying "this should be fixed now", or "just clear your cache" or "updates should now be updating instantly". 

Please fix.

I was able to add another test entry into your form. Changes was reflected on Preview and on your Live site. Please check your site again, I added "Jotform test" under "Instrument" dropdown.

Try clearing your browser cache or try it on another browser and see if that allows you to update your form.
