nyx "amount outbound connection" calculated wrong for 2 relays runnign at sema ip address

I do run 2 relays at the same ip address at different ports The stem example shows (corrrect):

mr-fox ~ # for p in 9051 29051 ; do python /usr/share/doc/stem-1.7.1/_static/example/relay_connections.py --ctrlport $p; done

A call of nyx, eg.:

sudo -u tor /bin/bash -c "/usr/bin/nyx -i 9051"

however shows about 7500 connections (Alt+S -> Connections) which seems to be the sum of boths. Netstat etc how that the command line values are right, Nyx is wrong.
