Possible bug - checkbox filter reset doesn't work as expected

-- HikaShop version -- : 3.1.1
-- Joomla version -- : 3.7.4
-- PHP version -- : 7.0
-- Browser(s) name and version -- : Chrome 60

I have a checkbox product custom field filter.
If I mark 3/5 options, the filter works fine. But then there is one reset button and it resets only the first from the 3 options, and I would expect it resets all 3. Please help.
I checked on two different sites and Hikashops and it's the same.

Hey,

Thanks once again for the patch.

One more question: is it possible to add a remove button next to every filtered value?
Example: if I filter by colors and select: white, black, red; and than I quickly want to deselect only red.
Now I have to remove all 3 filters and select white and black once again. And I would like only to deselect one, with one click.

That would be very useful.
Thanks for any help.

Thanks, that would be really helpful.
