ID 564098 - Soft Effects can separate from their TrackItem when using Nudge Up/Down, if there is more than one SubTrack

Problem summary:
Soft Effects can separate from their TrackItem when using Nudge Up/Down, if there is more than one SubTrack
 
This issue occurs with the Nudge shortcuts (Alt+comma and Alt+period) or Nudge menu items (Timeline > Nudge > Nudge Up/Down)
 
Customer reported version:
Nuke 15.0v2
 
Customer reported platform:
Windows 10
 
Steps to reproduce:
1) Launch Nuke Studio and navigate to File > Import File(s)... to import some footage.
2) Create a new Sequence, and then add a Clip to the Timeline.
3) Add any two Soft Effects to the Clip, which should now look similar to this:

4) Use Nudge Up/Down to move the Clip to different tracks, and observe how the Soft Effects become disconnected:

 
Expected behavior:
Using Nudge Up or Nudge Down should move the selected shots up/down while maintaining the relative positions of all Soft Effects.  
 
Actual behavior:
If there is more than one Soft Effect on a Clip, or more than one SubTrack in a Track, then Nuke Studio's Nudge Up and Nudge Down functionality will separate some Soft Effects from their TrackItems:

 
If the Clip has been automatically selected by the Playhead, then the disconnected Soft Effects can be overridden and deleted by additional Nudges, like the Transform Soft Effect in the example below:

 
Workaround:
No known workaround at this time
