I see that you are using an extremely old UBB.threads stock Style version.
You may want to update to the equivalent version of that for your current version of UBB.threads. It has several known formatting bugs that have since been squashed.
The style "ubbcentral" you are using is from UBB.threads 7.0. It has been updated and renamed to "UBB70"
