Do you know why the bit depth is different in column and different at the bottom bar.? And which of them is the actual bit depth.?

If you look carefully, you'll note that it says '32 bit mixing' - no mention of the file format in that. The files listing is correct, and so is the mix depth indicator. Unless you specifically choose an integer-based mix (generally a bad idea) then by default, you get the internal working format - which is 32-bit Floating Point.
