Draw Circle Tangential, 2 Circles, Radius missing solutions

I can only seem to get two of the four possible solutions to drawing a circle with Draw/Circle/Tangential, 2 Circles, Radius.

I placed two circles with a radius of 1 at 0,0 and 2,0. I then did Draw/Circle/Tangential, 2 Circles, Radius. Set the radius to 3. Moving the mouse up and down the y-axis shows two solutions: (x,y): 1, 3.87298 and 1, -3.87298. The solutions of (approximately) 1, 1.7 and 1, -1.7 are not shown. Is there a way of getting this to show?

This is LibreCad 2.0.7 on Windows 7.
