Missing links to games manuals files that were externally scraped

I am using the Skraper app to scrape game images, videos and game manuals.

When I use "Update Gameslists", it correctly adds the images and video for the games that I scraped using Skraper. However, it does not add the "View Game Manual" link in the "Game Options(Hold)" menu. It also does not show the small book icon in the game system folder to indicate that a games manual exists.

I have enabled "Search for Local Art".

I checked the ROM folder for the game system that I scraped and can see that the "images" and "videos" folder was correctly placed in the top level of that folder. The "manuals" folder is also correctly placed in that folder and the manuals files exist and are correctly named.

I can use "Edit this game's metadata" to manually specify the location of the game manual file, but that's going to be a considerable chore if I have to do it for hundreds of games.

Have I missed something? Apologies if I haven't explained the situation clearly, and please let me know if I should provide more information.

Hello
Can you show us an exemple of your gamelist (just copy the content between <game> </game> tags) , and some screens of the concerned folders ?
