Issue with Glossary widget in Captivate 8

Hello,

I've started exploring the Learning Interactions in Captivate 8 and am having an odd issue.  When I create an interaction (in the this case a glossary, it fills the full 'frame' of the object.  When I add items (and then delete the auto filled ones), it resizes the interaction to only fit about 3/4 of the 'frame' leaving about a quarter of the frame empty at the bottom.  I can't seem to find anywhere to fix that?  I can stretch the object so the blank part is outside the slide but that seems like sort of a clunky manual way to do it.  Any suggestions would be greatly appreciated.

Thank you!
