VoiceOver reads everything twice

Hi everyone, I experience strange something.
I'm running iOS 18 developer beta 7, but even before VoiceOver behaves strange.
Wen I'm working in English VoiceOver reads and shows in Braille every sentence twice.
Its happens wen I surfe on the Internet.
In edition, VoiceOver doesn't read me the level heading.
On my Braille Display the level heading doesn't show me.
Somebody has this issues?
I tried to restore my settings, but after a wile it returns again.
My phone language is Hebrew but I'm working with 3 aditional languages like English as a second language.
