Bug with clicking actors/media libraries listings when looking at movie info?

I have four libraries, each containing a copy of La La Land. All four libraries have their Visibility set to “Include in home screen and global search.” On the La La Land page in Discover, it shows all four libraries as sources. However, on Ryan Gosling’s credit page, it only shows two libraries. Furthermore, under the La La Land poster on Ryan Gosling’s credit page, it only lists one library as the source. See the attached image.

All four libraries use the same agents and settings, and they comply with the FAQ requirements. However, two of the libraries do not appear on the actor’s credit page.

And when I search for La La Land, results from all four libraries appear. It is only on the credit page that two of the libraries are not displayed. Additionally, for some reason, one of the libraries appears twice as a source (It might be because that library has two different versions of La La Land. Although they are merged into one item, it appears twice).
