Multiple refresh events when having multiple filters

[gbrian]

I guess there's an error when managing multiple filters. So I'll move slice.setFilter out from the loop, don't you?

Good catch, yeah it should really just set the filter that has changed, I'm going to push a fix.

Many thanks,
I still setting up dev environment and playing around.
Next time I'll try to create a PR.
