Problem with change language module

Hi All,
When I install change language module and try to use it I get the following problem in the language version, which is not with checked "language fallback" checkbox.
About us[Main language missing]

And the flags always open the index page for the two languages..


Any idea what can be the problem?

Thank you very much in advance

In frontend or backend?

In back end.. but I found that the problem is in the new version.. it is not compatible with version 2.6.3 of typolight.. when I try version 0.6.3 of changelanguage module it works.. may be for future I have to use latest release..
