"Summary" is used as teaser text instead of episode text


I’m having a problem that most likely is theme related, but perhaps someone can help me as I’m somewhat hitting a wall here.

For some reason my theme (Oblique Pro) seems to be ignoring the normal episode description when it comes to the teaser text on our own starting page. Instead the “Summary” text is used. Problem is I cannot really use the Readmore-Tag or anything here, meaning that the text is not clipped at all and usually very long, which looks somewhat strange. As long as I’m correct though that summary is used on external sites, which means I shouldn’t clip it myself, right?

I’d be super grateful for any kind of help, though I know this is probably a very basic issue.
