Problem standardising re-classed raster

I am trying to standardise (0-1) several re-classed rasters (re-classed to 1-7).  When i use the ('raster' - min) / (max - min) in raster calculator it gives an output with values which are either 1 or 0 and nothing in between.  It looks to take all the elements in 1-6 and make them 0 and the values in 7 it makes 1.

Anyone have any ideas where i might have gone wrong??? Its incredibly frustrating, I'm fairly new to Arcmap.

Many thanks
