@tk415 :
I assume that , You have a form once you submit this form , it its success you are redirecting thankyou page. and then these many wcmmode gets added as params. Can you check below.
1) when you click on submit , do you add any params to the URL while it is redirecting to the thank you page
2) Did you develop any custom JS code on submit button component
3) Is this issue happening only on this page or able to see same issue while you are redirecting to thank you page.
suspecting,there is some logic has been implemented to add wcmmode=disabled if its author environment , so some check is missing here and logic is keep on executing.
Thank,
Siva
