Subtitle font="Arial Regular" function loading incorrect font

[poeBaer]

When inserting a Subtitle, and trying to set the font value to "Arial Regular", the output is that of a different font

Eg:
Subtitle("Test", font="Arial Regular") loads the Courier New font

However, other Arial fonts appear just fine

Eg:
Subtitle("Test", font="Arial Italic")
Subtitle("Test", font="Arial Narrow")
Subtitle("Test", font="Arial Narrow Bold")
Subtitle("Test", font="Arial Bold") though "Arial Bold" is the default Subtitle font, and will also load under Subtitle("Test", font="Arial")
