[PyMOL] Problem with intra_fit

Hi all,
    I have a problem with intra_fit. After reading two (or more) pdb 
into the same molecule, it does not recognise atoms for other states. I 
always get the message (this is for a short example):
PyMOL>intra_fit name ca, 1
Executive-Warning: Missing atoms in state 2 (0 instead of 2).
Executive-Warning: No matches found for state 2.

even after executing:
PyMOL>alter all, chain =''
Alter: modified 24 atoms.

How can I know what is different in the two states or why the selection 
doesn't work?
Thanks,
Ramon

I enclose two pdb files as examples that do not work.
