Key names of dimensions in DataSourse

Hello,

I'm developing my application in SAP BusinessObjects Design Studio, ver. 1.6.

There are few datasources. I 'm doing some sort of filtering data in "Initial view" section

and some other places. But I got an issue with key names. It looks a bit complex

(for example "_nI0i09CjEeW0cZFstvnvBw").

Picture 1.

I have created uneverse via SAP Information Design Tool (ver 4.1).

Also i thought that it caused becase dimensions' name are in Russian,

but i tried to change it to English and it didn't help.

I have searched through sap.com and got one link

http://scn.sap.com/community/businessobjects-design-studio/blog/2013/12/31/my-first-design-studio-dashboard-application-over-a-universe-data-source

there is a chapter "Let the “Drag and Drop” layout design begin".

Keys look correct on picture (obj_2, obj_4, obj_6).So I think a solution is possible.

Please give me advice what should i do in Design Studio or in  Information Design Tool

to change these lables.
