You have more than one ski pass per day in your profile.
We assume that each user has his own profile on skiline.cc. This implies that no duplicate ski days should be entered for users. However, for some ski days this is the case, if additional ski passes of other people are entered. For this reason, duplicate ski days are detected automatically and disqualified (see pink triangle next to the ski day).
Note: Disqualified ski days will not be included in the ranking.
