Autocomplete is more annoying than helping.. Possible to reset ir or desactivate

Hello,
I have often trouble when renaming tracks in the artist field, autocomplete force to the old spelling or suggest other thing like if there & collaboration in the name on other records… which happens quite often for instance in jazz. For instance if a band name was write in capital letter and you do not want that, that’s impossible to correct it, autocomplete will always correct to the old version… same when you mispelled or accidentally leave a space before or after the name. Is that possible to desactivate this annoying “feature”. Tried to add a space or underscore before, it’s works, it let me write the name correctly… up to i remove it.

Is there a possibility to desactivate that? Or reset the memory/cache?

That’s really annoying detail…

Thanks if you have a solution…
