Unable to equip glyph

Hi there! I was excited to receive a specialty glyph for rogues, “rogue flurry l” but am completely unable to equip this glyph! I can see it in my inventory, but when I select to equip a glyph from the character screen, I am showing an error that there are no glyphs available. Could I be trying this wrong? :face_with_hand_over_mouth: thank you for your help!
