Advertising Headline Error

Hello, the advertising headline is displayed incorrect. Sorry I'm not shure if this is the rigth term in english. I'm talking about the small section below the image slider with the button on the right side. The bottom line of this area cuts through the text and the button. I have exact the same content on a test domain. Now I like to redo all on the production domain and there it looks different even absolutely everythin is exact the same. My problem it is now 00:44 AM and I have to finish it before daylight! Maybe somebody can help. I would realy appreciate this. Greetings Ralf
