Preroll ads and the video playlist

I am placing custom made ads (not using VAST or any ad service) through the FV FlowPlayer settings to preroll before my video begins. Everything plays fine, the ad rolls and the video plays right after. But I am noticing a problem with my playlist. After the ad plays, the next video in my playlist becomes highlighted, even though the first video in the playlist correctly plays. As a result, the first two thumbnails in the playlist play the same video (the first) and the last thumbnail plays the second to last video, leaving the actual last video unplayable. Is there a setting I need to change so that while the first video in the playlist is playing after the ad, that video remains highlighted in my playlist? Thanks in advance.
