Thanks Birbante.

"In Luna the files equivalent to the Phoneme are found inside the map, they are the .gph files, but I think they are not active, (mine are not active), you see it in Main Menu / About / Content / Phonemes."

This is the right answer.

I deleted 4 .pgh files _NA.gph, _NA_vr.gph, Canada.gph, Canada_vr.gph and seems fixing the problem.
