SCR50AXE and GS1915-8 - Double topology error on 2 different sites

Hello everyone,

As you can see I installed inside 2 different sites 2x SCR50AXE linked to 2x GS1915-8 that are used to manage small LANs.

On both of them I see double cable connection between the security router and the managed switch, instead of only one cable:

Of course I have WAN linked to internet and only one LAN port linked to internal switches:

• SiteZ

• SiteP

Both are showing this typo:

”br-lan” <>3

Seems to be a duplicate of this one:

How can I solve that?
