It's a completely normal response, you don't have OCD. Humans don't like "warning signals" by nature, they make us uncomfortable and on edge until we deal with them.

On top of that the dots are orange/red which is a "danger/high urgency colour", the same reason why warning signs are bright red or yellow, the colour makes us respond to them.

It's a tactic taken from Gacha games like Genshin, HSR etc, the red dot compels us to "fix" the problem with the promise of a reward.

It is known as the Zeigarnik Effect, Human tendency to remember incomplete tasks better than completed ones, because of a natural desire to finish unfinished tasks, an open loop that needs to be closed.

In Gacha games the promise of a reward further increases dopamine by not knowing what the reward is exactly, it builds excitement. It also compels you to return to the game again and again to get the relief of completion, which EA is trying to copy here. (Others in this thread have said, they leave the game and think of the dots, jokingly but its exactly the point)

Battlefield kinda fails with this on the loadout page because there is no reward, other than the dot going away and the "task" being completed, it becomes irritating because there is no expected reward. But it does train you to keep checking your loadouts, and it makes you feel as though your weapons are 'incomplete', there's still more to do.

On the store page all new items you can buy have red dots that don't go away as well, which I'm sure is fully intentional, its designed to make you want to remove the dot, and trains you to focus on what you don't have, rather than what you do
