Narrative:

Checked route and legs against the flight plan and TRISS2 RNAV departure during the before starting engines checklist. On climb out after capturing triss the next waypoint became txk instead of shero (shero had dropped out leaving no discontinuity on the legs page or break in the magenta line. Did not notice until several minutes after capturing triss when informed by ATC. This event is totally my fault for not monitoring the sequencing of waypoints against the paper departure page.
