The mod works great, and I love it. However, despite having a valid list of filtered tiles the minimized list is empty, it shows the buttons, and the number of tiles, it lets you use the < and << keys but the coordinate list is empty. I've used this mod for a long time, and this has always been true. My work around was to maximize, select a tile, then minimize and repeat. It got very frustrating and when I saw what it was supposed to look like on the manual I was determined to fix it

I disabled all mods and only loaded base game plus this mod, same deal. Then I started messing with game settings and I think I finally figured it out. It is the UI scale setting. For some reason you can't see the minimized list on 1.5x UI scale, but you can on every single other scale including 1.75x. This is at least true for my computer running the game windowed borderless at 2560x1440. So if your minimize list is empty despite having a list in the maximized window, try changing your UI scale. Seems like a fairly rare issue but it was driving me crazy! I searched the forum first and saw a few people very rarely complaining of the same thing. So hopefully this helps someone else.
