A CSS definition causes a wrong layout of the Confluence 'Tip' macro. This issue will be fixed in the next release.

For the moment you can use the following workaround:

Insert this stylecode into your global Administration > Stylesheet section to fix the styling.

body .success {
  color: #333;
  text-align: left;
}

#givemedalcontainer .success {
  color: green;
  text-align: center;
}
