Xgen - 3dpaint tool doesn't display the map

[Anonymous]

When I try to change my density, region and all the other maps, xgen displays an orange border around my mesh and pink points. I can't see my black&white map or red&green. The brush still works so I can make changes to the map, but I can't see where I am painting so is useless. 
I already tried to assign Lamber, doesn't work. 
I am using Maya 2018

Please, can someone help?

Solved: I found out that by selecting each time that I need to make a change the scalp geometry the map appears again.

Another quicker way is to use isolate select, is on the viewport toolbar so is faster to use.
