Spacing problem in guest list

There seems to be a weird problem with the spacing of the "icons" in the guest list. When we sign in to our account and click on one of our events to see who has signed up, there is always strange spacing in the guest list right beneath where it says, "10 positive responses..."

Just wondering if you could look into this. It puts 3 or 4 guests together in one row, then it might only put 1 guest on the second row, then 2 or 3 on the next row.

Is this by design?
