AiMesh Topology shows an empty page on RT-AC86U

[Rares Oltean]

Like the title says, I'm trying to setup an Asus AiMesh with my RT-AC86U being the master but when I access the Topology tab I get an empty page.
First time I tried with the latest Merlin FW 386.11. Then I tried, 386.10, 386.7_2, 386.5_2... same thing.
I tried reset to factory settings with all of the above. No dice. I still get an empty page.

I'm fresh out of ideas.
Can anyone help?

I managed to solve it.
Flashed the plain vanilla Asus Firmware to the router and did a factory reset. Only after these two did the contents of the Topology page reappear.
Doing a factory reset on Merlin did not do the trick. Neither did any other combination of flashing and/or resetting.
