iOS Question removing and updating a key from a map when value is null

[mkh_fx]

I have a very strange problem removing or updating the key from map when value is null
Although there is a key, it has not been deleted
It should be noted that this code works exactly on b4a

Dim mpTest As Map
mpTest.Initialize
mpTest.Put("gender",Null)       
mpTest.Remove("gender")

In B4i mpTest.Put ("gender",Null) does absolutely nothing (it does not remove previous value and it does not create new value).
