I can confirm the Style Influencer problem.
I tested without mods, cache cleared, new save game and a new created family, 4 Members (no On-/Offline Gallery Sim)
After that test I used MCCC to get some more information (logfile)
These Style Influencer are generated when you click on a Computer/Laptop. You don't have to use the Computer/Laptop. Just click on it. (I'm talking about a mouseclick btw., PC)
I clicked with everyone in the family (4 Members) on the computer:
[Jul-17-2025 14:41:27]* Created homeless household, Krause, containing 2 sim(s) for: filter_computerChat_Style_Influencer_Freelancer_Fashion_Photographer
[Jul-17-2025 14:41:30]* Created homeless household, Kreitz, containing 1 sim(s) for: filter_computerChat_Style_Influencer_Freelancer_Fashion_Photographer
[Jul-17-2025 14:41:33]* Created homeless household, Gutenberg, containing 3 sim(s) for: filter_computerChat_Style_Influencer_Freelancer_Fashion_Photographer
[Jul-17-2025 14:41:35]* Created homeless household, Vogel, containing 3 sim(s) for: filter_computerChat_Style_Influencer_Freelancer_Fashion_Photographer
So the game created a new Influencer for every Sim. (Overall 9 Sims in 8 seconds)
That Influencer doesn't appear in the friendlist, but does appear in the travel-friendlist (without relationship bar)
If you delete that Influencer, the game generates a new one next time you click on a Computer/Laptop.
If you delete just the relationship (MCCC) the game also generates a new one.
The game forces you to have a relationship with a random generated Influencer (Career lvl 1)
At least if you want to use a Computer.
