URL Version Problem

[oxylife]

Our Online store http://www.mygetwellstore.com has issue in URL.

Magento is generating URL versions by padding suffix number in URL-KEY.

Please help me.

Example.

System is generating URL versions one after another for the same URL(specified). Whereas it is unique, system generates versions if any thing conflict(same) in its database.

Please check this.
