How can I restore missing top icons and access purchases in App Store on High Sierra iMac?

Hello,

I'm using my iMAC 27" for processing photos and other stuff. The MAC was recently reinstalled. When I open App Store I'm missing the top menu in the header of the app. Does Apple removed this feature so I can't no more access apps that I bought? Without access to purchases I can't install anything just applications I downloaded from internet. Tried connection from my ISP, then VPN and then mobile carrier internet. So it's not connectivity issue.

System is High Sierra 10.13.6 and I'm running this because I need some older apps like Aperture, Affinity Photo and others. Computer is fine mid2011 3.1GHz, 32GB RAM, 2TB SSD. No other issues just with the App Store. Tried safe boot, but didn't helped.

Does High Sierra have access to purchases from App Store or it was dropped? I mean I bought various software so I have the rights to install it despite of older computer and system. Is there any other option how to access purchases for example from CLI?

If I decide to install Linux those apps are not ported to Linux as well as not for Windows so I would prefer to run the Mac OS.

Firstly there was missing icons, but text was present for example purchases, updates and so on. Now the text disappeared too. I'm attaching screenshot. On 2nd January it was working fine. Yesterday I found it's missing. Is there any solution how to fix this?

Thank you for answer. Feel free to ask anything. Have a nice day.

Samuel.
