Thank you for the quick reply.
So I’m doing. I’m still writing bug
Name page: Zprost?edkování
link: https://akmtrans.cz/zprostredkovani/
H2 content: Zprost?edkování – zbo?í, materiál?,…
always 86% the same mistake – Page title word in content heading
The problem is Czech accents – Zprost?edkování – zprostredkovani – seen as another word.
Your plugin I like to translate it into Czech and see what happens.
