How to remove link from Iframe Widget

I am trying to remove the "Bids Already Received" section under 1st Grade - Mrs Castano.  I've deleted all coding for it, but for some reason it still keeps appearing.  

Thank you for contacting us. Would you kindly clarify if you meant "Castano - Bids Already Received" instead of "Bids Already Received".

If you meant "Castano - Bids Already Received" then I see it has not been removed in your form as illustrated below.

Have you tried using css?

#label_29{

display:none;

}
