Increasing measure length puts the add'l beat in the following measure; can't fix

1 Select a measure in the middle of the piece. (It is the selected one in the screen shot)
2 Go to measure properties and change from 2/2 to 3/2.
=> Note where the newly-added rest is added - you now have a half note rest replacing the first 1/8th note of the next measure.
3 Use Undo to try to fix the change.
-> Note that the rest has been removed but that the first 8th note of that second measure is still missing. (Measure properties report it as a normal length 2/2 measure. There seems no way to fix this measure.

I would call this a Min severity item except I can't seem to be able to fix the measure that is now 7 eighth notes.
