Flashcard Grid

I am trying to arrange the tiles evenly and am not able to figure that out. I want two on top, two on bottom.

I researched and found the below, but mine does not show option #3.

 

Step 3: Add, Delete, or Reorder Cards and Switch Block Types

1. To add a new flashcard, click Add at the bottom of the flashcard list.
2. To delete a card, hover over it in the list and click the trash icon that appears. 
3. Reorder the card list by hovering over a card until the handle icon appears on the left-hand side of the card. Then click and drag the card to where you want it.
4. Click the X in the upper right corner of the sidebar to close it.
5. Convert your flashcard grid to a flashcard stack and vice versa by selecting the block type from the drop-down menu that appears when you hover over the flashcard block.
