DT 3.0beta4 - Invisible characters - bug?

Using a RTF or plain text, invisible characters markings are appearing where there aren’t any such in the text. eg, line break in the first tine at ‘on’ and line break at the start of the second line. (If it helps i have set the left and right hand margins and line spacing to my requirements.)

I attach screenshot.

The same issue is on the default format, per second screenshot.

Another bug? When showing invisible characters, all the settings in the format bar (shown) are disabled. I have deliberately hidden my sidebar folders, etc so as to provide the attached screenshot.

The next release will fix this.

Noted, thank you.
