Ubuntu 20.04 upgraded from 18.04 - snap software is not decorated

In fresh Ubuntu 20.04 installation KeepassXC looks like it’s been presented at it’s snap package page.

But in upgraded from 18.04 version it looks like at the attached screenshot.

I think, the issue is not upon KeepassXC itself, it’s some ‘global’ decoration issue. Please, help me to understand how to fix it.

Some additional info:
