Duplicate mac address eve-ng bug ?

Hllo,
I'm experiencing issue with a node that doesn't want to start (I have actually more than one node having this issue, but let's take node 18 as exemple).
I noticed that this node (ID 18) has the same MAC address than another node (ID 13) found in files /sys/devices/virtual/net/vxxxxxxx/address

vnet0_18 ce:93:20:bf:18:69
vunl0_13_32 ce:93:20:bf:18:69

I tried to stop the lab , restart the server, but I still have the same issue. The mac changes, but it is still duplicate, see below after a stop/start of node 13:

vnet0_18 2e:3b:29:81:d7:cc
vunl0_13_32 2e:3b:29:81:d7:cc

All the nodes that have an issue to start have a duplicate address with node 13 (they were working fine some weeks ago)
For sure I could remove node 13 to confirm it is the culprit, but this is a big node with many interfaces that I'm a bit reluctant to rebuild.
Is it a known bug ? Is there a way to clean the mac address assignemnt ? I'm using community (so I know that setting statically the first mac is not available in this version) ?

Thanks.
Rich

Nor vnet or vunl mac address are used in labs.... Consider those mac as switch port mac...

Real mac are visible on nodes only....
