Usually the new items go to the end of the list - very convenient to keep track of what is newly deposited. After the latest patch (May 8, 2024) all categories there (Daily Special, BS Adventure, Login Reward, Ancient BS Adventure, etc.) are sorted (looks like) by item type. For example, today's "[Event] Enhancement Help Kit III" went somewhere in the middle of "Login Reward" subsection.

I noticed this too. Kinda annoying.
