Hi,
1 - By using a "zoom" in your browser, the display of the grid of the backend is not aligned correctly.
2 - The result of the page is correct but as you can see in your page, your blocks do not have the same height ; so when you are using CSS rules like "float: left", that kind of display is expected.
Knowing that your are in a ul/li mode and not in "div", the bootstrap class names are not used.
I recommend you to provide a link to the page so the support team will be able to see directly the page and the CSS.
But my main recommandation would be to not use the "ul/li" mode in columns ; that's not the goal of that mode and ul/li and not made to do that... but Div are
