Thanks @viking for checking it out!
I don't know if this can be helpful but Platform view 5 is the only one which isn't affected by this and shows the proper description for each category.
I really like the clean look on this, but I have an issue with the platform category view.
Instead of picking the description of each category from their "Notes" saved in their metadata, it seems like it's searching inside the actual platforms. I noticed that because they are all empty (Consoles/Handheld/Computers) except one, Arcade, which shares the same name with one of the platforms. Here's an example:
BTW the description on the Arcade category is not the correct one, but, like I just mentioned, it's coming from the Arcade platform.
