Forms sporadically NOT displaying within toggle widgets

On our support page, we have 10 different forms embedded within toggled content (10 toggles = 1 question per), the page is below:

http://optronics.com/service-and-support/

Sometimes when you look at the page, none of the forms will display, sometimes it's 1 or 2 (or more) will not display  and sometimes the forms that don't display change so there's no consistency whatsoever, sorry.

I realize this is a lot of forms on one page but it's never been an issue before, did Jotform change something? Is there a limit to the amount of forms you can embed on one page? Perhaps these particular forms are taking a long time to load? When I "inspect element" within the browser it shows the one line of script embed code but the form is not there...

Any ideas why this is happening?

Hello,

I made some tests and I'm able to see you are saying, also I see you are using the default embed option.

We suggest to use the Iframe embed option, you can find further help here :

If after making that, you are still having the issue, contact us and we will be glad to help you.

Regards.
