-  * The underlying picture shows two places in the layer boundary where points are overlapping in the XYZ dimension. The point legend describes with yellow color that two points are overlapping at each location. +  * This setting "within the table" will possibly be more prefareble to use if only one or a small amount of layers has been manually edited.

-  * It can be doublechecked+  * Further it can be argued that if doublepoints exist within the table it will almost always be in the XYZ dimension because it is most unlikely that points will be made inside the layer which in that case could generate double XY coordinates.

There are multiple locations with 2 overlapping points according to the legend.
-  * Note the difference between the profile in step 2.1. and the underlying profile. Here, three new overlapping points can be observed tied to the wells that wasn't apparant before in the profile from step 2.1. This difference can only be ascribed to a different vertical position but with identical XY coordinates. The most likely interpretation correlates to points snapped to the vertical oriented well for a layer boundary in another layer that results in overlapping XY points.+  * Note the difference between the profile in step 2.1. and the underlying profile.
