I think it has relationship with the rules (law) in your country.

And for me it works fine, the only problem is with 5Ghz which shows only 4 channels for my region (Greece) 36,40,44,48 is it normal? ac connectivity seems ok.

List of WLAN channels

as i read its not normal to see 4 channels only on 5Ghz ,on Greece,i should see from 36-140, i smell some kind of bug in this beta FW, BUT yesterday i get my new LG G3 and tried to connect it on 5GHz ac , i got a Rock stable 433Mbps without a single drop for almost 24hours, and signal in the same place (same room) 2db better than the 2.4ghz ,but after i left the room things changed drammaticaly (which is normal for this band)and outside my home i could see only 2.4Ghz signal, the point is that 5Ghz ac connectivity is Fine with this FW, if you have no problem that has only 4 channels enabled on this band.

Because i cannot upload a bigger file due to page limitations, i explain....
the first 2 bars are the Archer c7 signals, first is 5Ghz and ch36 and second 2.4Ghz and channel 6, you can see the difference.

Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC) is required to use channels greater than 48 !

5GHz is not better than 2.4GHz for long distances...

you mean that i can enable the missing channels on my archer c7? if yes how?

No because I think the DFS/TPC feature not implemented on the TP-Link routers...
