I create a new Design.
I define a Label with a Content of TWO Lines.
Say
"Raum
Etage"
I then duplicate the Label
And define a single line content to the new View. Say "Width"
But in fact it is saving
"Width
Etage"
The 2nd line is still there.
If i mark the new view "Width" can be seen in the Properties Text value.
If i do doubleclick on the Textproperty the value is changed to
"Etage"
I MUST go over the ... Button to go to the Multilineeditor and to remove the second line so that the View is behaving as expected again.
This is not exactly a bug and it is the same behavior as in previous versions.
The duplicated label text has two lines, this is expected. The property grid shows a single line for the text (all items show a single line). This is why you have the option to show the multiline text dialog.
Note that you can press on the down arrow button to move between the lines.
