Agree.Same here

MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.moviesDetails.find({“rated”:“PG-13”}).pretty()
MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.moviesDetails.find({“rated”:“PG-13”}).count()
0
MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.moviesDetails.find({“rated”:“R”}).pretty()
MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.moviesDetails.find({“type”:“movie”}).limit(3).pretty()
MongoDB Enterprise Cluster0-shard-0:PRIMARY>

But when i select all fields can see “PG-13”

MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.movieDetails.find().limit(3).pretty()
{
“_id” : ObjectId(“5c4d2110dd0c40e56fbc3904”),
“title” : “Once Upon a Time in the West”,
“year” : 1968,
“rated” : “PG-13”,
“runtime” : 175,
“countries” : [
“Italy”,
“USA”,
“Spain”
],

MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.moviesDetails.findOne()
