I'm using the Datepicker in several places on the same page of my React application. In all of them, I have the i18n parameter enabled to customize the language. When this parameter is enabled, only the first instance works correctly; from the second instance onwards, the first day of every month always starts on a Monday, making the days of the week not match reality.
To solve this problem, I have removed the i18n parameter and am temporarily displaying the calendars in English.
The first instance works correctly:

From the second instance ondwards: July 1st, 2023, was a Saturday, and the 7th was actually a Friday, not a Sunday

Can you give me a hand?
Thanks for your help
