I am getting a "undefined" message in the upper-left corner of some of my forms

Some forms are showing the error, and some aren't.  They are cloned from the same base form. What would be causing this?

Hi,

We apologize for the temporary glitch. A recent update on our end causes this.

But we had reverted and fixed it immediately.

Please try to re-login to your account sigmapi1897 at http://www.jotform.com/login and check again if issue remains.

Inform us if issue persist.

Thanks.
