InsertMany () query : Difference between Compass and Mongodb Shell output

I deleted the document from the previous lecture(InsertOne()). So, I started insertMany() on a clean slate. However, I noticed that after loading the example in the InsertMany() handout, 4 documents were inserted when viewed on Compass, and 2 on Mongo shell output. can someone explain the reason for this?

I think you could refresh the Compass then the display will be displayed with correct data, there is a button to do it.
