Is this a bug or normal ?. (ArrayInitialize(); function)

[Hapu Arachchilage Tharindu Lakmal]

I want to reset my arrays. so I use ArrayInitialize(); function. the function has different types. but no matter which type I selected it only shows the char type input parameters. 
why is that?. The array I want to reset is a double type.

I have selected the double type. but still shows the char type input parameters. why?

Click on the signature to select the variant of the overloaded function you need

[EDIT]

But this only applies to the tooltip. If you remember the signature, then you can simply type the parameters without paying attention to the tooltip.
