If you select him with 2 generations the display gets corrupted. Can you extract his gedcom part and append it here, so I can test it?

Sorry for the delay.
clippings.ged.txt
I suppose this candidate (a second wife, without real data)
Bernard.ged.txt

Further test give a hint:
The second wife of Bernard is N.N., handled as special case.
When renaming the surname (perhaps to DoNotKnow) the bug is gone.

The problem no longer seems to exist in the current development branch (https://github.com/magicsunday/webtrees-descendants-chart/tree/2.1). Is there a way for you to test this? Unfortunately, I won't be able to create a new release today or tomorrow.

[arbor95]

seems as if its gone there. Only thing is, the presented name is now N. instead of N.N.

[arbor95]

std webtrees shows N.N.

Should be fixed in latest version in branch 2.1
