UNSOLVED RSS Feed wrapDescription // multiple lines

[schlittrix]

Hey guys,
i am new in this Business but I got a Problem with the RSS Feed function called wrapDescription.
I activate the Description below the headline, but the Option wrapDescription doesnt work anymore.
I also tried Width: „100px“ and read about a solution with CDATA. But this function is too difficult for me.

So is there a solution I did wrong with wrapDescription?
My code:

{
                        module: "newsfeed",
                        position: "middle_center",
                        config: {
                                feeds: [
                                        {
                                                title: "Der Betze Brennt",
                                                url: "https://www.der-betze-brennt.de/service/feeds/dbb-news.xml"
                                        }
                                ],
                                                wrapDescription: true,
                                                showDescription: true,
                                                updateInterval: 20000,
}
