Dots on grace notes misplaced

Enter a note
add a Grace 16th
Add a Grace 32nd
select the Grace 16th and press . to make it a dotted 16th

Result, the dot is after the 32nd note
Expected, the dot should be after the 16th.

Here's a picture of the results. It's difficult to see, but the dot is partially under the half note rather than after the 16th note.

I've see the same results with other dotted grace notes.
