Tutorial on how to hire your own sims you made, to work in your Restaurant

I've deleted every sim that's in my way of hiring who i made for the job,
As you shown above, in the "not in world" section.
However,
I have 3 sims that keep coming up when looking for new employees. I want to delete them, but they are no where to be found TO delete them.
Is there something that i'm over looking or missing?
