[Bug Report] `Notes -> Convert -> Switch Sides` leaves leftover notes

[Rudyrue]

Notes -> Convert -> Switch Sides doesn't seem to get rid of the last note in a selection despite switching all of the selected notes properly

To Reproduce
make a dance double chart
put 4 notes on the left side (1234) and 4 notes on the right side (5678), each one being later than the last
select all of them
click Notes -> Convert -> Switch Sides

Expected behavior
should properly switch every note over without accidentally having leftover notes

(not really a screenshot but i feel like it showcases the issue better
