Unlocked item missing

Hi all…allowed me to introduce myself…I’m M.Khor (name in zwift) from malaysia…I rode road to sky up to alpe du zwift peak yesterday (25/4/2020) and unlocked lightweight meilenstein wheelset…I saved and logged out…unfortunately today (26/4/2020) when I logged in, my wheelset missing…I reconfirm is my data really saved by looking into zwift companion and it is saved…but how come the item I unlocked went missing? Any encounter this problem before?
