Tweet this button not counting old tweets

Hello,

I just installed sharedaddy onto my wordpress.org blog and love these buttons! However, because I am moving from a blogger site to wordpress I was hoping that all my facebook and twitter counts would be included upon adding sharedaddy. So for example on my blogger blog I also had facebook and twitter buttons that both had their counts (each would show a number of facebook likes and number of people who had re-tweeted). So my hope in adding sharedaddy is that these counts would remain and still be visible, however only facebook likes are showing but not my twitter ones. Is there anyway the I can get the twitter to show? Currently it’s set to 0 on all posts but I know I had lots of tweets before for these same posts when they were on my other blog…

Thank you,

Kind regards,

Mara
