V157b responsive classic

When I add comments to update a customer order status it looks OK but when I send the email it is not wsywig, there are additional empty lines added to my comments; the standard zen cart beginning and end in navy are OK.
When I go back in admin and check the comments they also now have these additional empty lines.

My text editor is CKEditor.

I use the same text editor with the same settings to write product descriptions with no additional empty lines added.

Here is a test in the German language, I get the same effect in English; maybe I can configure the text editor somewhere?
