Bulk Handler Contact import doesn't import anything

There is no way to import contacts with CSV file. The Bulk Handler module shows contacts and validate them as good (green lines), but after "finished" button is pressed, nothing happens. There are no new contacts imported. 

Tried to import them to an External Group.

Also tried to import in UTF8 and windows 1252.

Well, is quite simple to understand what happens: It simply doesn’t import anything, although the registries appears to be correct for import.

This is what I do step by step:

1.- Create a group and two contacts, from FreePBX pannel:

9.- But nothing happens beacause the same old contacts are show without the new ones:

10.- Doesn’t seem to work and it happens to me in FreePBX13 and 14 (the only ones I have tried)
