Incorrect output for viewshed with 2 points #22

Using QGIS 3 and Visibility Analysis v 0.6.3 I get an issue when I have two points in the same layer.

I create a viewpoint layer containing both of the points and run the viewshed analysis on that layer. The output I get is a layer with 2 colors, max value of 0 and a large square way south of my two points that is black.

Using the same method but starting with a single point in the original layer works perfectly.

I work in EPSG:3006 (SWEREF 99 TM)
