Group width issue

Hi, I have been using Taskbar Tweaker for awhile and have an issue that I'm not sure if it is a bug, or if I've done something stupid. I went to click on an icon on my taskbar, and for some reason, now the group is showing only a minimized icon of the item instead of the full name... even when there is plenty of room on the taskbar. I have gone through options, and nothing seems to fix it, so I don't know if it's something advanced, or something I'm just not noticing. The icons go back to their normal, not minimized nature, like the rest of the icons in the screenshot.

I have a screenshot here: http://i6.photobucket.com/albums/y230/mistressnonny/windows_screenshot_zps1feadfb0.png

Help?? Thanks so much.
