Calendar object height is compressed

I'm using VizLib Calendar 1.8.0 and I have noticed that the object height seems compressed and smaller than other objects like the VizLib Filter object. Attached is a screenshot that shows how it looks in my dashboard and you'll notice that it's smaller than the filter object just to the right of it. The strange thing is that I just added this object to the dashboard this morning and it looked fine then. I then left the dashboard and came back to it a couple of hours later, it then noticed it looked compressed. So I don't know what caused it to look fine originally and then change to the compressed view you see in the screenshot.
