Bug: Replace With Notify option not fully functional

When you select multiple notifies and attempt to replace them with another notify using "Replace with Notify", it will sometimes replace other random notifies and not the ones you have selected.

Place any notifies of the same class into two separate tracks.

Select all notifies and select "Replace With Notify"

Notice that only the notifies in the first track are replaced

Select all notifies in the same track

Notice that either

A: Only the first notify is changed

B: Only the clicked notify is changed

C: Only the clicked notify and / or some random notify is changed
