V$RMAN_BACKUP_JoB_DETAILS output different for different nodes

 Hi Experts,

For 2 node RAC database, we are running backup from node1. Output from V$RMAN_BACKUP_JoB_DETAILS is running but at same time output from node2 for view V$RMAN_BACKUP_JoB_DETAILS is failed,

Any idea how come this is happening.

Node 1 :
