Bug found in filters?

[Boullie]

When filtering I encountered (what I think is) a bug.

I'm more of a keyboard-user, so hardly use my mouse.

When I was filtering my languages I clicked with the mouse in the field to unselect the languages.
I clicked on "Russian" (to unselect it).
Afterwards I pressed the 'arrow down' key and hit "space" to unselect the following.
These steps I continued until all languages (except English) were no longer active.
I saved the filter.
Yet, when applying the filter, only the Russian cards were removed.
When going back to filters, also only Russian was disabled (hence the only one I disabled with the mouse click).

Confirmed. Fix will be available with the next update.
