Another possibility is Excerpt and Excerpt Plus have two view modes, one when the name link feature is off and one when the name link feature is on. Here’s the description from the Template product page:
Excerpt Plus is the first of our templates to be released with multiple views. What is this, you ask? I’ll try to explain…
Connections has a feature that can be enabled that changes the entry name to a link, this link will take you to a page with just that entry. Excerpt Plus is smart enough to know if you have that feature enabled, which is on by default in Connections 0.7.6 and newer. If you have this feature enabled, the fade-in effect the reveals the rest of the entry’s bio is removed and replaced with a link to that entry. When you click thru to that entry, the entire bio is shown, there’s no need for your visitor to click again to reveal all the full bio.
Is this what you’re experiencing? If it is, that is by design.\
Hope that helps.
