Source Han Sans not displaying correctly at specific weight

In the document "Developing & Deploying The World’s First Open Source Pan-CJK Typeface Family" (https://blogs.adobe.com/CCJKType/files/2014/11/iuc38-lunde-s1t3.pdf#page=21), Source Han Sans does not display correctly at a specific weight.
However in a very similar page from another document "Building Source Han Sans & Noto Sans CJK" (https://blogs.adobe.com/CCJKType/files/2014/11/iuc38-lunde-s8t1.pdf#page=50), this is displaying correctly.

There is displaying issue on page 20 in the first document (See screenshot) but I don't know if it's related.
p.s. I have both fonts Source Han Sans & Noto Sans CJK installed if it matters.

"Reduced" test case available at: https://www.dropbox.com/s/2y1ddj67w8hlmhj/issue5476_reduced.pdf?dl=0.
Note: the problematic font includes a font file that is >10 MB, hence the large file size despite this being a reduced test case.
