Yes, you should definitely keep iterating, it seems like the solution is just starting to improve a bit (decreasing residuals). Continuity for example is still at about 10e-1. A good rule of thumb is to have 10e-3. I am still curious that your mass imbalance is still so far off.
Regarding the reversed flow, where is this occurring? The console should identify the surface. If you create a velocity vector plot, you will see where/why this is happening.
