Current items: 99 gjallarhorn, 90 daurdabla, new Harp Terpander (99 Bard)

I traded items for the Terpander, - Cehuetzi Pelt (7m), Ebony Harp(farmed/made), a Shofar (300k), and 150 Beitetsu(farmed/got from friend).
Waited game day to pick up.

ran down to Port Jeuno by HP1 and try testing songs and marcos:
-equip empy (daurdabla) harp sing 3 songs paeon 1-2-3
-equip Terpander sing paeon 4. No add song- Rewrote over song

Why does Terpander not do as labeled? No where does it say --- Adds 3rd song
No its said; Grants an additional song effect
