Missing 3 level of code stripping in player settings for Android

In Unity 2017.1 i not have 3 level of code stripping (Use micro mscorlib) and also my game build crash when i perform save if i use one of two available stripping options (Strip Assemblies or Strip ByteCode (iOS only)). Reset of player settings not make 3 stripping level available. Who know this is intended or bug?
