What is the difference between these two enum enums [Flags] (C #)

This is more of a question that I ask to understand, not to find out the problem. Consider the following two:

[Flags]
    public enum Flags
    {
        NONE = 0x0,
        PASSUPDATE = 0x1,
        PASSRENDER = 0x2,
        DELETE = 0x4,
        ACCEPTINPUT = 0x8,
        FADE_IN = 0x10,
        FADE_OUT = 0x20,
        FADE_OUT_COMPLETE = 0x40
    }

[Flags]
    public enum Flags
    {
        NONE = 0x0,
        PASSUPDATE,
        PASSRENDER,
        DELETE,
        ACCEPTINPUT,
        FADE_IN ,
        FADE_OUT,
        FADE_OUT_COMPLETE
    }

If I check something with the help of the last enumeration, sometimes overlapping occurs (I think something seems to be DELETEinterpreted as PASSUPDATE | PASSRENDER, whereas in the first example each record is independent of the other (i.e., it DELETEjust DELETEcannot be proved with combinations of another set of flags).

Without explicit numbers, the number of instances increases by 1 each time (even with the specified one [Flags]), so you get:

[Flags]
public enum Flags
{
    NONE = 0x0,
    PASSUPDATE, // = 1
    PASSRENDER,// = 2
    DELETE,// = 3
    ACCEPTINPUT,// = 4
    FADE_IN ,// = 5
    FADE_OUT,// = 6
    FADE_OUT_COMPLETE// = 7
}
