one sidebar different blogroll results!

for some reason unknown to me my sidebar is generating slightly different code as revealed when using ‘inspect element’ and is functioning differently on different pages. the difference is copied below. the functioning code is using a span class and the non-functioning code is using a span id. i am at a loss. any help would be greatly appreciated.

thanks!
