Quantize tool not giving results I need in the score editor. What am I doing wrong?

[attaboy_jhb]

Here is what I have as my grid is set to quantize at 16th notes

and When I use my quantize tool to get 3 8th note triplets, it gives me this which is not what I want

I feel like I have followed the instructions in the manual thoroughly but something is wrong, how can I get 3 triplet 8th notes here?

Hi,

In this case I would quantize the source MIDI Notes.

The rest between the notes is problematic.
What Martin suggested will indeed correct the display of the tuplet in the score.
