can't Delete protection relationship

Hi,

Using ONTAP  9.x with two cluster having SVM data protection I can't delete data relationship. 
I get the following erorr message when trying to build a new relationship even though the previous SVM protection is not listed as part of the  "SVM DR Relationships"

Failed to create SVM relationship. Failed to create Vserver relationship information. Reason: Source Vserver "svmXXX" is already in a Vserver DR relationship with another Vserver in this cluster.
