Left side menu of accounts

I have 4 email accounts in K9 and when I go to the left menu to list them, 3 color icon dots appear in the top, my current account and then 2 others. But there are 4 accounts (different color icons) in the list and I would like to see if all 4 icons could appear in the menu at the top. When them there, it makes changing accounts easier.

TIA!
