Mike B. Anderson (again)

I've tried, twice, to add Mike B. Anderson as the supervising director to latest The Simpson episode titled I'm Just a Girl Who Can't Say D'oh. The system says that there is not enough evidence. I'm guessing that the fact he has been the supervising director for 244 isn't enough evidence?

I hope this screen capture will be enough. Image: https://d2r1vs3d9006ap.cloudfront.net/s3_images/1784656/RackMultipart20190410-70954-pp030b-Do_h_Supervising_Director_inline.png?1554913044
