It is a bit fragile to use padding for centering an item within a row. Can you
try the following which is more robust, and I think achieves the exact same
visual behavior? Effectively it removes padding completely, and lets the label
be centered by other existing rules (vertical-align: baseline).

#copies-settings .collate-container label {
  padding: 0;
}

Yes, this has the same behavior. Thanks!
