Same heights of the boxes in the Felx Block 1

Hello,

I have a problem with the Felx Block 1.

If the titles of the individual articles are the same length, the article boxes have the same height (see picture 1). But if the titles have different lengths, the boxes are unevenly high and that does not look so pretty (see picture 2).
How do I make it, that all boxes always have the same height without having to limit the title length. Ideally, it should look like Picture 3.

Here is the link to the pictures

thank you for your help!

Regards,
