I don't know if it's a CSS or configuration problem. I use the default Xenforo theme without modifications.
I noticed that when viewed on my cell phone, the badges look like this, a little above the date. I believe that only in some cell phone resolutions there is a layout break like this. I thought it would be interesting to inform you.
I don't know if the reason is that the original images are 512x512 and I added "1x". I don't know if that influences it.
And congratulations on the Add-on. It's super fun and replaces Profile Flair very well (phpBB add-on where I came from)

EDIT:
I would also like to suggest a feature.
Rarity.
It would be cool if we could add an option to activate the rarity of a badge. With this, we can place, for example, a badge that if 5% (or some value defined by the Administrator) of the total number of people have this badge, it will be considered rare, adding a small notification about the badge icon.
I saw this functionality in Invision and thought it was really cool.
