Brand, I am not a studio/lighting expert but have never experienced that with my set. What are you using as a light source? I have used flash and 500w workshop light direct reflection without too much shadow. Maybe direct sun would give that type of shadow?
If you are not getting harsh shadow from your light source then you should not get it from the reflector. The backdrop/background should also not be too near to the model. Moving the reflect further away should also help to reduce harshness.
My set was cheaper but it depends on what you can get in Bloem.
