How do I get my phone to.. not be dumb

So I know this is so silly but it annoys me. You know how on iPhone it will take a picture of a person and ask who they are? I have named everyone but I have a problem with it not recognizing that my identical twin nieces are different people. I named one of them… I don’t want to post their pics or names so I’ll call her Ellie. It showed me a picture and asked me who Ellie was so I named her Ellie.

Now there is a whole album with both of the twins under “Ellie” … my iPhone thinks they’re both Ellie and I do not know how to change it 😂 I tried and it wouldn’t give me the option and I was wondering if any of you knew how to fix this issue. Apple did not consider the fact that identical twins exist

The funniest part about this is that my moms doorbell camera understands they’re two different people and can correctly tell them apart but my phone can’t
