Undo of the "Format value _DIRECTORY" action fails. e.g.
1 Do Format value "_DIRECTORY": renamed %_directory%

3 See error dialog:
File "D:\renamed myfolder" cannot be renamed to "D:\myfolder"
Also a suggestion: it would be good if the Convert | Action results summary e.g.
0 of 3 tags formatted.
0 of 3 files renamed.
included e.g.
0 of 3 directories renamed.
