Group Calendar description area not bound by center column

I have the BuddyPress Group Calendar plugin working and we love it. The only thing, the description area, where we can enter an event description, has expanded to the right to overlap my right column. It's not a huge problem, but it gives the impression that something is not quite right.

Is there a fix for this? Perhaps no one was aware of it.

I'm running all current versions of WordPress and BuddyPress, and my theme is BuddyBoss, which is highly supportive of BuddyPress.

Any help is greatly appreciated.

Best Regards,
Kevin
