Measurement line disappears - no vertical profile

I have the free version and about to buy the Pro, but have a problem. When measuring on the 2D, I drew the line, but after I press the end point, the line disappears. The horizontal distance shows in the sidebar, but no line and no vertical profile. Earlier I tried it and I did get both, but no longer. Free version is still active buy the way.

Solved my own problem, signed out, then in again. All the lines showed up.
