Several issues when creating list

Hi there,

when I create a list using the shortcode generator, several issues occur, that make the list show up quite ugly.

1. The list is located too far to the left so that it stands out of the rest of the text.

2. The font size of list is reduced so that it dosen’t fit to the rest of the text.

3. The next paragraph after the list is edited directly under the list without any space between them.

How can I get rid of all these trouble?

Please see attached screenshot for better understanding.

Thanks in advance for any help.
