Extra Title Words Can't Be Deleted

We have some titles that have extra words appended to them and for the life of me I cannot figure out how to remove them. Is there a cure for this?

For example, on this page http://agcamera.com/4-camera-dvr-farm-ranch-surveillance-system/ the title is “4-Camera DVR Farm & Ranch Surveillance System : foaling camera.” and it should be “4-Camera DVR Farm & Ranch Surveillance System”, but I can’t delete the last words.

Any ideas?

Thanks for the help as we are ready to launch.
