#g+ #hashtag testing

It seems hash tag in #blog post contents not recognized by #g+ when sharing from #blogger. Even the labels will not be used as g+ hashtag.

What I have tried is to put the hashtag in the title and it seems worked.

Why there will be two posts in G+ when I publish in blogger?

Anyone know why there will be two #g+ posts being generated whenever I post on #blogger? Though they are not exactly the same, but both link to the same post in my #blog.
Is there any setting control this behaviour?
