Categorization lost when renaming file

Could you fix this issue the meantime??

I personally find XnViewMP very confusing compared to the classic XnView and therefore too difficult to use. The import of the “category.db” worked, yes, but resulted in a huge mess of categories. Also the default categories remained after this procedure. Very confusing I think. I believe that the current XnViewMP is still something like a Beta-Version.
