Generated Item Path in website

The path of items published on website is system generated…In the past an item ABCD in group “frozen” would generate a path /frozen/ABCD. Now a new Item ABCD would generate /frozen/ABCD-f3xf (a meaningless alpha-nummeric code appended to the item name).
What is the meaning/function of this.
An existing Item will properly function with the old code even if edited. But if "show in website"is changed to disable, save, and enable, the new path with be appended with such cryptic code.
Who nows the logic/functionality of this?? @umair

Did you find out why it is added?
I figure it makes no sens. Can this be turned off?

No…i never found out
