John makes a good point on data entry.

And in the original post, I think a critical fact stated is that BIAB “sometimes” plays it correctly. It’s an essential chord in Bossa Nova music and likely was recorded.

I’ve had some success second-guessing BIAB by supplying more chord info than requested. For example, I might do D9 instead of D7 to make sure BIAB doesn’t add a b9 or #9 to a D7 chord. Using my trick above, the b13, might work. Note that Dr. Gannon in general does NOT recommend this.
