Saddle bag potential design issue

I have a small topeak saddle bag to carry spare tube, tyre lever and multi tool. It has a bracket that bolts on under the saddle on to which the bag clips. I have noticed that my Toupe saddle is bottoming out on the bracket which potentially means the saddle isn't as comfy as it should be. I have now noticed that the Lyzene and some other makes bags just have a strap that goes through the rails.

Is this a known issue with Topeak saddle bags? Should I be changing it to one that just has a strap?
