ID 604150 - Exporting multiple XMLs, using the same preset, does not respect which tracks are selected in the Export dialog

Problem summary
Exporting multiple XMLs, using the same preset, does not respect which tracks are selected in the Export dialog.
You will see that all tracks are exported on the second XML, regardless of what was previously set in the export preset.
 
Customer reported version
Nuke 15.2v4
 
Customer reported platform
N/A
 
Steps to reproduce
 
1) Open Nuke Studio.
 
2) Create two sequences with multiple tracks. In this example, each sequence has 5 video tracks.
 
3) Right click 'Sequence 1' in the Bin view > Export.
 
4) Select Process as Sequence and select the Final Cut Pro 7 XML preset.
 
5) Select tracks 2, 3 and 4. 
 
6) Leave all other settings at default, then press Export.
 
7) When prompted, save the changes to the export presets.
 
8) Import your XML (right click in the Bin > Import > Import EDL/XML/AAF...).
RESULT: This should contain the correct video tracks.
 
9) Right click 'Sequence 2' in the Bin view > Export.
 
10) Select the (edited) Final Cut Pro 7 XML preset and press Export.
 
11) Reimport this XML and notice that all tracks were exported.
 
Expected behaviour
The tracks selected in the Export dialog should always be respected.
 
Actual behaviour
When exporting a 2nd XML, all tracks are exported, regardless of which ones are selected in the Export dialog.
 
Workaround
Deselecting all tracks, then reselecting the desired ones again, seems to export the 2nd XML as expected.
