Renaming categories should refresh category view

In my first run of Tidy Start Menu, I wanted to use the category wizard to adapt the categories to my already existing folder structure.
Accidentally, when creating a new category I mistyped the name (e.g. "audios"), and then renamed it again to fit the name of the existing start menu folder (e.g. "audio").

Now, the category wizard did not refresh the view of "audio"!

Only after clicking another category and then again this renamed category, the already existing items were shown.
