LogiCore DisplayPort v6.1 (Rev. 1) - Why does the option to select Quad Pixel remain disabled when changing the number of lanes from 1 back to 4?

Description

In the Vivado 2015.4 DisplayPort v6.1 (Rev. 1) GUI, when I change the number of lanes from 4 to 1, it disables the Quad Pixel selection. 

However when I change the number of lanes back to 4, the Quad Pixel selection remains grayed out (It cannot be selected). 

What is the reason for this and how can I fix this?

Solution

This is a known issue in the Vivado 2015.4 DisplayPort v6.1 (Rev. 1) UI.

This issue is resolved in Vivado 2016.1.

Please see (Xilinx Answer 66301) for a patch for the DisplayPort v6.1 (Rev. 1) in Vivado 2015.4.
