'''Housekeeping Units module - Table not being able to be sorted '''
Units can have two conditions in the table, for example a departure and an arrival on the same day. When this happens the table becomes complex and non sortable, There is an option for the module called "Group by Unit" the default is YES which is the current behavior. Switching it to NO will create a simple always sortable table.
