No thumbnails on some folders

After a recent update I have noticed that thumbnails don’t appear on some of my folders. When I open the folder the comic is still here with the thumbnail, but when I back out of the folder there is still no thumbnail making the folder appear empty. I have tried clearing cache and rebuilding thumbnails in the settings but it hasn’t fixed the issue. I know that it isn’t a big issue but I thought that I would bring it up so you are aware of the problem.

Thanks @MikeOxlong96
