@papy72 I was mistaken, I apologize. That indeed is Basic mode.
Basic is the "new" mod screen with Tips, and recommended mod sets, and a brief sentence describing why to use them.
Advanced is the "old" mod interface that we used prior to Mods 2.0.
The Red dots on them indicate the game wants to recommend something else. It's either; A - agreeing with what you have on the arrow and triangle, or B - you don't have any in your inventory that match what it would recommend.
If, in that basic mode, you click on a mod with no red dot, it will typically show you a "ghost" image of a mod with what it wants you to go find/farm/buy (i.e. none in your inventory that match).
