Event editing MASSIVE boxes

Good day

So having an issue on the edit of event stats. Not the stats themselves, but more an issue with how it’s displayed, attached below is an image of how the boxes to insert data is MASSIVE, obviously this is not the entire things, but can only capture so much on the screen, but regardless, please help, as this makes things difficult, and I have a feeling this might be an issue that might have been resolved in the past.

How do I share images, as I tried uploading, but doesn’t seem to work so I can show on issue (as issue is on backend, when logged in)

The page I need help with: [log in to see the link]
