It would help if you showed how it looks in the slicer.
But from the photo it looks like it made the bridge in a circular way instead of in parallel lines. If you can make the bridging go strictly in parallel lines from top to bottom, it should turn out better.
I would go back to your CAD model and tweak it for better printability. If it was a model you downloaded and without a source CAD model I would just remodel it myself to be more printable.
