Spacing between the title and the paragraph

Hi,

I have installed your theme on my website and I have a problem with spacing between the title and the paragraph, paragraph and photos.

Namely, when I publish my blog and want to edit it, I make double space between the title and the paragraph and when I update the post in some cases it works in some it doesn’t. In the same blog, I do the same thing, but it selectively performs the action.

I have tried everything even pressing shift + enter, or using the classic toolbar and twice enter (as it worked once) but nothing works and it’s a hell of time-consuming!

Once I managed to edit the whole blog and it took me hours of editing it. As I had misspelt one word, I went back to edit the word and all spacing was lost again!

Please help me with this problem that I have had from the start! It’s so annoying because it is simple but simply doesn’t work properly.

Thank you
