Stream order, only grid code 1

Dear all

I am trying to get a stream order network using spatial analyst. I have used the Stream order tool before and the result was a network with grid codes from 1 to 5. This time, with another DEM, I am only getting streams with grid code 1. I am using a flow direction raster and a flow accumulation raster (after Con tool, value > 1000) as inputs. In the flow accumulation con raster I can see all the streams, but after using the Stream Order tool some of these streams disappear. Please find the pictures attached.
Do someone understand why I got this result?

Linda
