Formatting upset after changing a single digit

Hello everyone

I’m looking for some help with our shopify store, and hopefully this is the right place, apologies if it is not.

Earlier today I updated a shop webpage. The page remains the same, the only thing that changed is pricing in two boxes.

The page URL is: https://www.sockgeeks.co.uk/pages/statement-socks-renew

There are two other similar pages which have the same issue.

I updated the price in the last grey box for a 12 month subscription so that the price increased from £60 to £69. In this case I simply changed the 0 to a 9, saved the page and bam! The boxes were no longer aligned in a horizontal line, and are now incorrectly staggered down the page.

Honestly I cannot understand what has happened here. I tried loading the page in the Shogun editor and everything looks correct there, but as soon as I preview the page or load it in a browser the boxes are no longer in alignment.

Any help appreciated in making me understand how such a simple change affected the formatting of the page.

Many thanks

Thank you to those that looked, but a colleague fixed the issue by making the text size 20 instead of size 22. I’ve no idea why this should have fixed it, as I never changed the font size to start with, but it did.
