Reproduction Steps:
1. Set a DXP with the latest fix pack and start it.
2. Go to Publishing --> Export and run an Export.
3. On the Export processes page change the display style by clicking on the icon next to "+" on the upper right.
4. Go again to Publishing and select Export.
Actual Result: The display style is not retained and changes back to the default one.
Expected Result: The display style should remain as it is.
Note:
The same behavior should be resolved in the Import section too.
