THESE ARE ISSUES: 1.Importing full article of feed works

THESE ARE ISSUES:
1.Importing full article of feed works fine but When I set any of the excerpt setting, the results is still *full* post being imported.

This is frustrating as I have to manually start going to add the More tag.

Please fine below some of the feeds I am using:
http://dailyindependentnig.com/feed/
http://www.bellanaija.com/feed/

2. it add this at end of the article posted on my site "The post Lawyer sues IG, FCT CP, N8M breach of human right appeared first on Daily Independent, Nigerian Newspaper."

3. Is there a way the "Link to original source" can show on only the full article display instead of in the shortened/excerpt version, this will drive visitors away instead of viewing the full article on my site via READ MORE.
4. Does the autoblog setting not auto-publish the name of the original Author in front end with the article.

Please your quick responses is need to resolve this issues.
