pink trinket not working correctly

Had a game on my smurf today, bought the pink ward trinket upgrade, kept placing basic trinket wards. Confusing to the max.

link to game, as you can see I bought the pink trinket. Placed multiple regular trinket wards afterwards. Took a screenshot, haven't had time to place in paint yet but the ward on the right (behind me) is mine. While I have a pink ward trinket. http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1931914891/144723?tab=stats
