Currently, when using Batch renaming for the very first time, the field "Filename template" defaults to "name-#". This preset is not so good, because it's not so clear that this is just a sample template and the using the enumerator "#" only once will not sort properly on older Windows systems.
Instead, the preset for "Filename template" should be something like:
"Sample-####"
or
"<Filename>-sample"
