Ghost of Saltmarsh Module not providing maps?

So I bought The D&D 5e ghost of saltmarsh a while ago and I and my friends are having a lot of fun with it. I haven't really had any problems so far until now, but I have run into problems with "Chapter 6: The Final Enemy". There are no maps. Every other module seems to load them just fine but the one module that has the biggest dungeon doesn't load any. I bought this so I wouldn't have to set up the dungeons, but is there something I forgot to do or I am missing a step? (So far I have tested this by adding different modules under "addons" to see what works).

The maps are called Level 1, Level 2, and Level 3 in the page toolbar. I just tried adding the Final Enemy addon into a fresh base campaign and they appeared just fine.

Oh, I see I had some other maps named similarly and didn't notice them because I am blind. Thank you for your help.
