Some Icons Missing

I just installed EmelFM2 in Kubuntu. Some of the icons display (Back, Up,
Forward, Home, etc.) and some do not (Panes, Show hidden, Filters, etc.)

I tried editing the config file with this, but it didn't help:
# use icons directory
use-icon-dir=true
# icons directory
icon-dir=/usr/share/pixmaps/emelfm2
