The most important thing is to get a shot of the rigging panel. If layers got renamed, it is possible that current triggers got disconnected from layers. In your recording, it showed the triggers and swapsets in the corner.
If you click on one of the layer names here, it should show beneath the layers it is bound to. Could you give a screenshot of that? If they are orange, it means the bindings have been lost. In rig mode you can reconnect them by dragging the layer from the rigging hierarchy to the trigger names above (you can delete any orange connections as they are broken and I don't think will reconnect by themselves). Or just create new triggers and swap sets.
