Can't change font size in iMovie

[marshmallow21]

imovie 10.0.6
OS: 10.10.1 (Yosemite)

Trying to edit font size but the bar as highlighted in the attachment won't work. I can go to show fonts on each subtitle and do font size changes but it takes so so long.

Can anyone tell me why the font size bar is not able to be changed right from this screen. Automatically set on 72 and can't select anything from it.

Thank you.

Shut down iMovie and restart your computer. I believe the new software Yos.....has a few teething problems with video software.

Didn't work but I found that if I select different titles, some allow for me to change font size from the bar, others do not. Weird!

Yes, that's the way it is. As you say, weird.
