if you see the names of parts, then why don't you change them in fluent? it will be the same.

This is a gambit issue and not a Fluent issue. It also happens for many other softwares as well. The problem is that the meshing utility doesn't properly setup the .msh file correctly. Behavior is also wildly different for 2D vs. 3D.

If you can at least confirm that all your boundaries are present, it's best to just re-name them in Fluent and not bother with trying to define/declare them in the meshing utility. A frequent problem is that a boundary surface (which is a wall/surface basically) gets imported into Fluent as an interior (a volume), and that is probably the most annoying issue to run into.
