World data for lot sizes: "UnreadableDataResource"

Just installed The Sims 4 Studio for the first time today using the newest version posted on this site and following the lot size guide led me too "World data". Clicking on it doesn't bring up the page shown in tutorials but instead the UnreadableDataResource page.
As mentioned, im incredibly new to this and its not intuitive so i have no clue if i have done something wrong or not.
Running everything including For Rent.

I dont even know which world file is for Sulani as they aren't named in any way that suggests whats inside that i can see, that file came up as I was following the example in the tutorial using the same world file just to learn the process.
