Icons will not appear on SharePoint Site

As you can see below in the Status column I have the desired colors in the correct manner however for some reason I cannot get the icons to work next to them, the originally worked and now they wont Am i being blind.

I’m sure its a super simple solution however I cannot seem to get it working again.
