Advent Calendar didnt count in objective

There is no door 5, it goes from door 4 to door 6.  You need to complete 6 times. There have only been 5 as of today, no reward for today.  If you look closely there is only 19 objectives and the 19th objective is door 25 for 25 completions.  Not sure why EA did not just do one objective for each day, it looks like lots of people are getting confused.  There are several other days that are also skipped.
