In the FLE enabled shell, it seems like BinData type 6 isn't decrypted as it should be when documents are fetched in getMore calls. When running an aggregation against the FLE-enabled shell which returns more than 101 documents, the first 101 are decrypted properly, while all the rest contain BinData. For example, one document looks like this:
{
	"_id" : "u49",
	"patient" : {
		"name" : BinData(6,"AYgJLpLd8ku+jV8arok6P4MCvO7xtz7j1/LauGMFhdUxX+SI+yu16CcSi8vRMOVyE1ngPSeI777Q1jq33H0AupCrbovf1AnNoJxMG9XoiS7KEg==")
	},
	"doctor" : {
		"name" : BinData(6,"AYgJLpLd8ku+jV8arok6P4MCXX2OS/ntRC87Kczz+iwaudQr95q0upAo3A7pifESuOw0NmjnMZIQsyKyzoKkYGMfiPjCcr7sIX4+j7lIcBI8zw==")
	}
}
When it should look like this:
{
	"_id" : "u49",
	"patient" : {
		"name" : "D6"
	},
	"doctor" : {
		"name" : "AA"
	}
}
