If I disable XPerl the cooldowns on the default Blizzard buff bar disappear, as shown in these screenshots. I can't find anything in the XPerl configuration that has anything at all to do with showing cooldowns on the Blizzard buff bar.

By default the buff bar has no cooldown spirals (remember OmniCC only shows countdowns over spirals). xPerl appears to be adding those spirals to the bar - not sure if intended, as I've never used xperl. Which addon are you using to move and hide the bottom text of the buff bar?

I didn't know there was a bottom to the buff bar so maybe XPerl is doing that, too. The timers on the Blizzard buff bar does appear to be an XPerl feature, albeit an undocumented one. Thanks for the response. :-)

Glad I could help!
