Description in the Flexfields differs form the Describtion in the Account

Hello,

I've got the following Issue:

I am supposed to set up the Accounts and Hierachie in the General Ledger:

General Ledger --> Setup --> Financials --> Flexfields --> Keys --> Value

But when I want to add Flexfield Segments Values, the description that is shown in the flexfield is different from the one in the Account:

How can I make it happen, that in the flexfield Segment Value appears the same description like everywhere else?
