Problem with editing artists

Hi. I’ve noticed a bad behavior when editing artists…
I’m editing my greek music.

as in general i want romanized name (also because in my file tags the names are romanized), i edit the artist:

the problem is that after that, i can clearly find the artis under the edited name, but i cannot find it anymore under the original (roon) name

this behavior is not very logical.
in fact the search engine very usually gives as results not only the plain searche text, but also hidden names (like real name, a.k.a., also relatives and so on…)
for example if i look for gordon summer, i get sting. that’s logical.
here, after editing, it seems that roon ignores any previous info related, and that’s not OK.

no answer at all?
