Filtering by a label doesn't work

[badsteel]

Filtering by a label doesn't work, neither in the dashboard nor in the address bar.

When I click any label in the filter window, I see an address string changed for a fraction of a second, like 'https://trello.com/b/randomsymbols/myboard?filter=label:MY+LABEL' and then it's again 'https://trello.com/b/randomsymbols/myboard'. The same happens if I type the first address manually. My board is loading in full without any filtering.

Well, the search string (in the upper right corner), like 'board:myboard label:"my label"' DOES work, but it's a terribly inconvenient way to search things.

UPDATE: Filtering doesn't work if a label is linked to less than 4 cards.

Changing Atlassian password solved the problem.
