AEM pathfield appending values without changing

I have a path field widget in AEM for error page handling.

I have added it at the base page implementation and when I try and select the path, I see that there is a "," appended to the path. If I clear the field and save, I see that the old path still exists. If I add a new path, I see that the new path is appended to the old path saperated by a comma.



Fig 1: Intially the error pages is coming up good.
Fig 2: After clicking OK and checking the properties again (Note the "," that is being appended)
Fig 3: After adding a new path (Again the path is appended after the ",")

Has anyone faced the same issue. I tried different forums but wasn't able to get any answers. The same configuration is working fine on my local but it is creating a problem when I push the same code to the server.

Updated
dialog.xml - Here I'm defining the tab where the the error pages path field is displayed

Best How To:
To answer, there was a pathfield node by the same name under foundation and I had overlooked it. Removed the node and it is working good now.
