Icon Issue

I am having an issue with my teamspeak server, i can see all the icons that i have put on, and i have assigned members with a group so there is icons like Member, CSGO, DayZ, Server Admin etc, but no one else can see them and only see a white page? although some people can some of the icons... which is weird only some not everyone can see but some can but only a few of the icons..

Here is what someone sees;
