I can see the problem... There is only one tab
Bicim 0 (ör. "1"
instead of two...
Go to the Catalog->Settings menu, and at bottom set the proper plural form.
See the proper plural form codes here:

You'll get two tabs at these strings where you'll be able to enter the single and plural form of the string.
