After having installed the basic components of Cobl (Cobl.esm and Cobl Glue.esp), I decided to move ahead and add Cobl Races.esp, Cobl Races TNR.esp and Cobl Races TNR SI.esp. I went to the new character creation screen just to see the implementations to the races and I noticed that Ren's Hair models are presented twice or even three times (i.e. Ren's Hair 06, Rens Hair 06, Ren's Hair 06, Ren's Hair 07, Ren's Hair 07, and so on). Basically, TES4Edit shows that Cobl.esm has multiple hair models with the same name (although the EditorID is different). Is it normal that there are such duplicates in the game, or which is the meaning of this?
