[Plugin: Tweet Old Post] Running Thesis and Tweets are showing HTML

I use Thesis and for those posts that have been assigned a “Post Image” via Thesis, the tweets are showing the HTML instead of the body text.

For example:

{Archives}: What We Did in Praslin (Seychelles) – [caption
id=”attachment_4212″ align=”aligncenter”… http://bit.ly/nZtzUE

For the posts that don’t utilize the Thesis “Post Image” option, the tweets show up just fine with the title, body, and link.

Anyway to remedy this to have the HTML not show? Please let me know if you need more details or examples. Thank you.
