Record producer multi variable set dialog blank after clicking add

[Roaf]

Hello,

I created a record producer with variable set (multi) the other day tested and everything was working fine. Today, I went in and clicked that Add button on the multi-variable row set, and it just shows me a blank dialog with the Title Add Row. 

Is this something happening to everyone on the platform currently ? 

Thanks.

happening with all the users or some users?

Any onLoad or onChange script is running on that MRVS which is breaking and causing the issue on SP?
