It worked for me (2017 build 3).

All I did was select the track and then run the option.

It could be that the midi file you tried it on doesn't meet any notes with the criteria defined in the programming.

The notes need to be of the same pitch, side by side and almost overlapping (or overlapping presumably). In those cases, the two notes are replaced with a single note.
