Activity of my computer isn't shown at my account page

Okay, I wanted to run some new GPU tasks on a host that hadn't been doing anything for some time. I changed the venue/location for it so it would get correct settings to download GPU tasks.

First strange thing here:

I see that light green graphic and message "The location for this host has been updated.This will take effect next time the host contacts the project."

Yep, but it didn't change at the selection box. It's still "Home" even if I changed it to "Generic". I repeatedly tried to change it (tried also other locations), but it's stuck on "Home".

Then I hit update for Einstein on that host. I see that location has been effectively changed to Generic and host receives GPU tasks.

Second strange thing:

That host is still shown at the very bottom of the list when I look at my computers. It has run a few tasks and uploaded them back now, but 'last contact' is Dec 12. If I click on the tasks of that computer, there's nothing about these tasks it's currently running.
