TextField already exists in Objectmap

Hello Everyone,

I am using Silk4Net with Rumba Desktop (9.5), Since we are using Mainframe (3270).

In Mainframe we have different Screens/pictures.

When I add textfield for instance from Screen "A" into my objectmap.

example below:

Then when I go to Screen "B" add another textfield, into my objectmap

the program says the Item name & Locator Path already exists,

Could someone help me 

Thank you in advance
