Condensing label problem, already known?

Sometimes after doing something with a condensing label in engrave mode (in this case hiding it, and then undoing it) it will still be selectable but no properties show up in the lower panel.

If I insert a condensing change and delete that, things are normal again.

Is this me, or something reproducable?

No properties show up even if you de-select and then re-select it?

No, nothing. I am trying to reproduce it but until now it did not show up again. If it happens again, I will tro to document it.
