[Resuelto] Date Translation Issue

Background of the issue:
I am trying to update the date format for Chinese translation on my WordPress site. I attempted to change the date_format from 'F j, Y' to 'Y/m/d'. The issue can be seen on this page: enlace oculto.

Symptoms:
I expected the blog post date to translate to '3月7日, 2025', but instead, it translates to '7 3 月, 2025'.

Questions:
Why is the date format not updating as expected?
How can I correctly translate the date format to '3月7日, 2025'?
