Bug NativeMultiHashMap wrong count in editor script (EditorWindow)

Hi there,

I'm using NativeMultiHashMap which itself works fine and give right count value, as i'm using it in a complex scenario so i visualized its values in an editor window and this is where problem happens.
count gives me wrong values like 19 when actual count is 5, even if i debug and add break point i get right count value however Editor Window shows wrong value.

What could be issue?

Please advise
