Looking around I found in batctl o the same mac as originator as the next hop.

root@da88:~#  batctl o
[B.A.T.M.A.N. adv openwrt-2019.2-7, MainIF/MAC: wlan1-mesh_252/78:a3:51:16:da:88 (bat0/7e:30:a4:a8:83:a9 BATMAN_IV)]

 * dc:9f:db:0a:15:34    1.420s   (193) 02:13:f2:16:d9:ec [eth0-2_252]

May this be the reason?
