problem with clsconfig

Hello. I have a small problem which delivers a lot of trouble:
If you change the xml starting with ID 16-31 characters per account with ID 16 and disabled import clsconfig when the server, new characters are the same as 16-31, but when you first log on them get a "base game has not received information about the character . "If I export the new xml characters 16-31 in clsconfig
./gamedbd gamesys.conf exportclsconfig
then the new clsconfig obtained the same as was previously (before starting editing xml). Same size. The same data.
Why?
