How to set up Previos/Next video buttons?

I have a RasPi with Kodi and for the life of me, I cannot get the Previos/Next buttons to work. I am playing videos from a HD attached to the Pi using Flirc with an old remote. All the videos are in one folder.

I had this working before but I have no idea why it's not working now.

If I use either the FF/RW buttons or the Previos/Next buttons on the remote with Flirc, All the video does is skip ahead. It does not go to the next video. I tried "Next/Previos track" On Flirc as well. Nothing skips to the next video. I installed keymap add-on and tried to map previous/next with that. No go.

This has to be a setting in Kodi, but for the life of me, I can't find it. What am I missing?

Thanks!
