Icons missing by view Host Group

I’v added 3 switches (no 9, 10 and 11) but the icons are missing by the view Host Group

which file needed to be changed after these files; hostgroups.cfg, hosts.cfg and services.cfg

Thanks in advance

hostextinfo.cfg
read all about it here:

Throw your icons in your images directory in your nagios webroot.

Icons are already in the images directory because they where used for the switches no sw1 - sw08. So why are they not displayed for the sw09, sw10 en sw11?
