Linux mint does not remember default browser

When I launch Chrome on Linux Mint, it asks for being the default browser. I confirm and it is remembered between browser relaunches. But when I shut my laptop down and then turn on again, default browser is not set anymore. Also, after I press _Set Default_ in Chrome I can see that default browser in _Preferred Applications_ is still unset. But if I set it there it is also persisted until next system restart only.
