Don't know if this has already been reported or not, couldn't find anything relevant searching through the lists.
Currently playing a game with 2 galaxies with 100 planets. It's coming towards the end of the game and I own all of one galaxy.
At this stage of the game the lists that show the collection rates for Credits, Metal and Crystal go a bit weird. Check out these screenshots.
This one is the crystal list

And this one is the credits list,

Maybe there needs to be some grouping or filtering or something on those lists.
