We have a pdf posted online that has a Web Page Title that includes Microsoft Word - and ends with .doc when viewed on a mobile device. I understand that this is part of the meta data, and cannot find a place to modify this. Firstly it is annoying that the .doc suffix would be included on a .pdf and Secondly, how do I remove the Microsoft Word Prefix. 

I tried to change the web options preferences, and under web page title no matter what is inputted we still get Microsoft Word and .doc displayed as part of the title name. I just need to change the title. Under get info in finder the title is listed as the same thing.... of course this is not the file name, I am having no issues with that. 

Hopefully this makes sense, I need to change the title name, not the file name. It needs to not say Microsoft Word in the title and not be appended with .doc as it is a .pdf and is reflected as a .pdf in it's file name. Please help... this cannot remain on our website in this manner. 

It's probably that I am so frustrated now, I may have put this in the wrong forum, this is for Microsoft Office 2011 for Mac.
