Customer CP - Broken graphics link in call history tab

When using the 'call history' tab in the customer CP, the blue and red box graphics next to the "VOIPo Number" and "External Number" legend markers disappear (broken graphics link) after clicking on the 'all', 'incoming' or 'outgoing' tabs.

Click on the main 'call history' tab again and they re-appear... until you click on the filter tabs again.

Good catch. In FF3 it just loses the color square beside the text.
