Closing the field space

I have an app where the space between fields is closed, meaning there is not any large amounts of space between them.
Example:


However, in making a similar app with similar fields, I cannot seem to remove the extra space between the fields.
Example (I have encircled in red the extra space):



I cannot figure out how I did it before and why I cannot do it now. Also, the Rich Text box is not expanding to fit below the three upper fields.

What am I missing? I feel like it is something super obvious but I can not place my finger on it ...
