Block TCP Scan with RST is the one you want uncheck.

As i see, this is too much for TP-Link support to fix it (or even reply here with question to fix it).

They can't add MAC to this anoying info from few releases (beta version have it).

 

But do you buy TP-Link staff to try beta software? I think no ;)
