This is similar to the issue seen in this thread: Re: CRUD read error on Cisco_IOS_XR_ip_rib_ipv4_oper. Please see that thread for potential ways to handle this.
The bug ID tracking this is CSCvd74932 and it should be fixed in the upcoming 6.3.1 release of XR.
Note that YDK is doing the right thing here (detecting duplicates in leaf lists). Some of these YDK scripts have help us identify issues in the NETCONF/YANG implementation in XR as you can see in this case.
