Concentration (Condition) is not removed at the completion of spell duration

I created an ItemMacro based off of the Dfreds CE Faerie Fire spell and it works: the spell visual effects and gameplay effects (advantage) are removed after 10 rounds, but the concentration effect is not removed from the token (either on the token itself or in Dfreds Effect Panel) - Dfreds EP shows an orange clock and marks concentration 'expired' but it is not removed. If the same actor casts another concentration spell, I am asked if I want to end concentration.

Dfred's Efect Panel icon:

    if (lastPlaced && lastPlaced.document) {
        lastPlaced.document.delete();
    }
}
