Why does Simulink not give correct results with load inductance for 3 phase controlled rectification?

Hey, I was trying to simulate a six pulse three phase converter using simulink. It gave me correct results for the six pulse rectified output but on the inclusion of source inductance to the phase source I would expect to see some commutation overlap(u).However what simulink provided was no where close to those results.
- I have attached images of the 6-pulse converter without the source inductance(which yields correct results) and I have also attach the 6-pulse converter with source inductance(which should yield some commutation overlap in the output voltage).
- I have also attached the simulink .slx file named "ThreePhaseNormalSourceWithRLoad.txt" rename to .slx before use.
I hope you can throw some light on the matter,I am rather puzzled at the output.
(Also note that the Load inductance has been kept high to receive a good ripple free output current, this also helps in easily identifying the commutation overlap).
Thanks.

NOTE: The included .slx file is uploaded with .txt extension as it cannot be uploaded with .slx
Also my matlab version is 2017.
