Missing spacing in some areas like button of calendar and badge preview area

1. A recent change resulted in the spacing of the "Add to Calendar" button missing.

2. There is some unwanted spacing issues in the "preview badge" box on the organizer wizard. There should be a spacing above the line.

Unfortunately the changes implemented also changed the width of the buttons and spacing to the left and right.

Goal was to solve this:
A recent change resulted in the spacing of the "Add to Calendar" button missing.

Before. The only requirement was to fix the spacing below "Add to Calendar".

Now - spacing was changed everywhere and looks out of place. Spacing below "Join Event" button was also changed and is slightly too big now. The date and time suddenly takes up 5 rows in this resolution and the buttons are shorter than before. This issue solved one thing and created other issues.
