AX1800 RAX10 in AP mode

Hi

I recently purchased the Nighthawk AX1800 RAX10. I'm running it in AP mode and so far everything seems to be working. But there is one thing that annoys me and that is when when looking at which devices that are connected, it doesnt shows all the devices connected via Wi-Fi even though I have continoues pings running through the AP to the devices not showing up in the list. I have of course refreshed the view. The wired devices are shown correctly. 

Anyone experienced the same issue?
