I'm having the same exact issue as you. I've tried everything I can think of but still no success and the 5ghz Band 1 is consistently disabled.I tried the latest firmware upgrade, I backed up and tried a reset, then I tried a complete factory restore. Still nothing.

Model : Hardware Version : Firmware Version : ISP : Hello, After updating the latest firmware, my router's 5GHz Band-1 stopped working. Band-2 is working perfectly fine. Whenever I am clicking on 5GHz network, it is saying that 5GHz network is not available in your country/region. This is totally insane. It is available and widely used in India. Your support executives also told me the same. They are totally out of clue as what has happened and why band-1 is not working. I purchased the router to have Tri-band but now I am getting dual band support. What the hell is wrong with TP-Link? Do they even test firmwares before releasing it to public? I even found same thread on this forum where someone is complaining about the same. It seems it's a fucked-up half baked firmware which was released to public. Shame on TP_link, this is going to be my last product of TP_link unless and until they come up and resolve the issue.
