All options in settings not displaying properly?

I have notice some partially hidden checkboxes in several places in Studio settings.

When I open the File types option in Project settings, I noticed that some of the checkboxes don't appear for some filetypes, no matter how much I expand the window.  F. ex. in the pdf/MS Word 2007-2003 Common settings, it seems there is a checkbox missing at the end, I can see only a small part of it. I can actually check it and uncheck it, but I don't see the label.

I have seen this in other places in Studio. In Project settings in Batch Task for Translation memory update (in  the Segment status area) there seems to be a seventh checbox, which I can't fully see.

I found that often I have to expand the window even to notice that there are options, because there is no sidebar to indicate, that there is another option I can't see. So sometimes I actually don't know that I am using a particular setting.

I experienced this in both 2014 and 2015 version. I can see options display properly on a different computer but don't know what PC setting can be causing this.
