Hi @SB,
This problem is also related to Multilingual Online voices (as you had a similar issue with Multilingual Online voices last time). As far as I have tested, I can only reproduce the issue with Multilingual Online voices.
For now, the workaround is still to use non-multilingual voices. I would suggest you also send feedback (Alt+Shift+I) to let the Dev Team know about this new issue. Thanks for your understanding and support
