Can't add innr products

So after a little while now i noticed my flows aren’t all working that well. Lights turn on / off when not intended. Or half of the lights turn on / off when it needs to.
Was looking around and found this thread.
I decided to go check out my zigbee page on the developer page and it looks like this:

And if i’m right this isn’t good. Because everything is added as a router instead of being a proper mesh network. So this might be the issue why i have these weird issues.
But then again, i had issues even adding anything. So putting my zigbee in the same room as the devices i could finally add them.

What i’m gonna do now is take screenshots from my flows. Delete all the zigbee devices and add try to add them one by one from their final place in the order i would think the mesh network should function.

Also: i thought i read somewhere that smart lightbulbs couldn’t function as routers since they’re voltage is too low? But here they are shown as routers. Was i mistaken or is this yet another weird issue?
