RH4 with three 8port Nodes sync Problem

I´ve some Trouble with our consoles (v3.10.0) or perhaps our Mapix nodes. I´ve 3 artnet nodes from Mapix with 8 Outputs to DMX. The node runs on 40HZ
I have patched every node with the same DMX Adresses. Artnet out 1 is DMX Port 1, Artnet out 2 is DMX Port 2 and so on. The console runs in broadcast. The console have a fix IP 10.0.1.14, the nodes 10.0.1.3, 10.0.1.4 and 10.0.1.5
If i flash a cue the Outputs on the nodes don´t come together, it´s like a chaser, the Outputs are not sync. You can see it in my Video.

Did the consoles send an artnet sync command??? Any idea to solve the Problem?
