Joomla Free extensions

I installed JO K2 Auto Facebook and it is working fine. I could share K2 Items to personal profile, pages, and groups from k2 admin item section and it is wonderful. Unfortunately, after installing JO K2 Auto facebook, my normal facebook share buttons stopped working. When somebody reading news items and sharing news story using K2 Social Share button or other 3rd party social share button to facebook, no title, description or image showing up. It just show raw link and website name. Please advice me how to overcome it. ....
