Offer attachments - getting added automatically

Content

Hi All ,

         When i extend an offer either by email or eOffer , i see an attachment being added automatically , in the "Send Offer Letter" box . This specific attachment is getting added regardless of the req or the candidate . I verified this specific attachment is not attached to a req nor is it coming from the paragraphs that constitute the offer letter template . 

Does anyone of you have an idea where it may be coming from .I tried to find any settings which may drive this behavior , but was not able to find one .
