previous section profile will be used

Now its time to ask this one: ;-)

Always when I change a cross section sketch in a drawing to make it for instance coincident with a point (in this case placed manually on the midpoint of an edge) I get the message "previous section profile will be used", see attached.

The horizontal line is the cross section line being replaced.

I usually ignore this, since when I close the sketch it still does what I want it to do.

Can anyone explain why this message comes up?

Is my practice wrong here?

Thanks.
