I haven't been able to reproduce an issue here.
I did find "and " with "& " and saw that it worked fine in a folder name.
Then I manually renamed a folder to "2003 &" and was able to edit the name again in Explorer.
Any other details, like an exact input filename and set of parameters we should test? You can export the settings you're using on the Rename, Move, & Copy dialog using the 'Preset...' button.
Thanks.
