Missing Purchased Forest Guardian Costume Parts In List Of Available Costume Parts

I unlocked Forest Guardian Legs #2, Forest Guardian Chest #1, and Forest Guardian Arms #1 and #2 on November 24, 2024 using Cosmic Keys obtained through the Cosmic Key Of Power Nightmare Pack and Cosmic Key Of Power 10 pack I purchased from the Z-Store along with an additional 5 Cosmic Keys Of Power I bought. I successfully unlocked the aforementioned costume parts but they still do not show up in my list of available costume parts at the tailor. After submitting a ticket and going back and forth with the Arc Games Support Staff I was given Forest Guardian Legs #2, Forest Guardian Chest #1, and Forest Guardian Arms #1 and #2 costume parts in my inventory as a courtesy. I tried unlocking the parts again bit received an error message stating that the parts are already unlocked, but they still don't show up when I go to the tailor. In addition, I received and unlocked the Forest Guardian Hips costume part during the first week of December 2024 and it does not show up in my list of available costume parts either. I have had problems for the last couple of months with purchased or unlocked costume parts not showing up when I go to the tailor. HAs anyone else had this issue and can someone help me resolve it?
