Newly unlocked attachment markers don't display on attachment slots

The red dots/markers which indicate newly unlocked attachments on weapons, added with update 1.1.1.0 (Season 1 release), don't appear on attachment slots.

That means when you customize a weapon with new attachments, there are no red dots on any attachment slots, so you have to check every attachment slot to find what new attachments you just unlocked, negating the convenience that the red dots were supposed to provide.

Some weapons aren't affected by this bug. The red dots appear on attachment slots on the following weapons that I tested:

• GRT-BC (carbine)
