Sub Pages with similar names ... in different Pages

Hi:

New to ZOHO services ... been playing around with ZOHO Wiki ... very impressed with it so far ... will be using it to create a Resource (tips, articles, code snippets etc.) for other ZOHO Creator developers.

Noticed that ZOHO Wiki does not allow Sub Pages with similar names ... even when the Sub Pages belong to different Pages e.g. ...

Africa
- Cities
Asia
- Cities

... will not allow the Sub Page named Cities under Page name of Asia.

Am I doing something wrong ... or is this a restriction ?
