Break Lines spacing

Hi,

Some of my break lines are giving a big gap between the lines like a paragraph. Can you please look at the sshot below and the page where this can be obtained to see what the problem may be and how to fix it? This also happens in the “Marker Tooltip” of a map.

I am afraid that fixing this will ruin other sections where a double line may be required. Is there a way to have single and double line spacing by simply adding one br/ or two br/ (i.e. pressing Shift+Enter once or twice) to get a single or a double break line?

Either way, the main priority is making a regular break line without the double spacing.

Thank you
