Pouch cannot be stored on Server

Because you didn't read the item description properly, you have to open the shooting star pouch first before obtaining another pouch which contains a skila pouch that can be put on your server storage

[Lans Vahndreas]

It's clearly mentioned in your posted picture. "The [mission box] can't be used in server storage." And in your inventory is "Shooting Star Mission Pouch Lv. 2" which is should be named as "Mission Box".
So yeah, it wouldn't be able to be stored in Server Storage unless u open the Mission Box to take the Skila Pouch.

Yeah my bad sorry for not reading it
