Replacing selected text deletes wrong newline

[MBoonie 8]

On the Evernote for Windows app, I have a series of lines that each end with a newline sequence.  If I select an entire line and then press Enter,  the selected text is replaced with a blank line as expected.  However, the newline at the end of the *next* line is also deleted causing two lines to be joined.  I've attached "before" and "after" screenshots -- the only this I did in between the two was press Enter.
