Mongo doesn’t shrink previously allocated structures because that would slow database down. When you need it, run the repair procedure to rebuild DB and reclaim unused space. On live project you should schedule it to off-peak hours.

From the command line:

mongod --repair

From the shell (you have to do for all dbs including local if you go this route):

db.repairDatabase();
