Excerpt has line-break in sidebar but not on homepage

Hi

I am trying to make the excerpt look the same on my sidebar and on my grid layout blog posts on homepage. On sidebar the excerpt cuts into two lines since I have two lines on the excerpt box with manual line-break (enter)

But on homepage the excerpts just squeezes into one long sentence without manual line-break.

I tried to use various excerpt modifying plugins and also check if I could change the css but I guess I have to do something else? :)
