Sims Get the Moodlet from removed trait in CAS

If you change the traits of a Sim you have played with at least once, the Sim get the Moodlet about removed trait. I've never see this issue in no play Sim. ( I don't play a Sim down loaded from Gallery.)
The similar issue reported in this boad:
Sim is getting Loyal Moodlet despite not being Loyal | EA Forums - 11917161 
And in archive:
[OPEN] Lovelorn Moodlet without romantic trait | EA Forums - 11402187 
I had this issue about Music Lover and Romantic trait.
In the archive thread, the workaround also reported (mentioned by Zack4358). I tried the workaround and that's successful.
In the both of the threads, no one reported about "removing trait", so I creat new report.
