Duplicate content causing error in backend configuration page

[love jreviews]

image attached, 

 

i have three listings, of which are practically the same product, the listing resource that has been added to each one has been copied and pasted, is there a way to allow duplicate content within the listing resources addon for jreviews?

 

ive attached img for you to see the error in the backend, once clicked on the add resource listings addon in the left hand menu..

 

thanks!
