I have an Airport Express 2nd Generation (Version 7.6.8) that I'm using as an access point for my desktop PC.
My house has a Technicolor DPC3848VE modem and WiFi router with dual-band network.
I set the Airport express to connect to the 5GHz network (the networks have the same name + 2.4 or 5.0 for differentiating them).
All the connection is done without problems, but when I check the Network Icon in the Task Bar, the tooltip says I’m connected to the 2.4GHz network.
Just to be sure I did a factory reset and connected the router again and it still connects me to the 2.4GHz network.
How can I fix this/force the airport to only use the 5GHz network?

Your computer will use the wifi best suited under current reception characteristics. If you want to force your windows computer to only use the 5GHz wifi, you'll have to remove the 2.4 GHz from the known networks as for example detailed here for Windows 10 (which you appear to be using judging by your screenshot): http://www.ilovefreesoftware.com/24/windows-10/remove-saved-wi-fi-networks-windows-10.html
What you could do is configure both wifi's with the same name and let your computer switch automatically (works way better when they have the same name), that way your laptop would choose the 5 GHz one when close enough to the Airport and choose the 2.4 GHz one when further away
