Issue Solved.
I Noticed That I Had Broken Sims 4 Mods From QMBIBI. The Broken Mods Were Causing The Adult Milestones To Appear Twice In The Milestones Section In The Sims 4. I Deleted The Broken Mods From My Mods...
There Is A Bug That The Adult Milestones Are Showing 2 Of The Same Milestones. It Should Be Only One. This Is Not Good. Yes I Do Play With Custom Content And Mods. I Play On PC.
