Not enough margin when filter blocks are added one on top of the other

[Aljullu]

To reproduce

1. Add a Filter by Attribute block and a Filter by Stock block to a post or page (add also an All Products block somewhere in the page).
2. Set both filter blocks to have the Apply button visible.
3. Preview the post in the frontend and notice the button of the first block is too close to the title on the second block.

Expected behavior

There should be more margin between filter blocks.
