Is there a reason some categorical vars are left out in Rossmann

In the list of categorical variables (cat_vars) in the Rossmann dataset I noticed that a number of the columns are not included in either cat_vars or contin_vars and was trying to understand if there is a specific reason for this.

For example, Is_month_end, Is_quarter_end, promo2sinceweek, Open …plus others, are all not included in the final list of variables that are used to train with.

Were these found to have no correlation in a previous training and then removed or is there another reason these don’t get included?
