Acf field in new widget

Hello,

I have a strange issue with acf fields repeater and template elementor.

Let me explain :

i have single template elementor with inside my custom widget used for a custom post type.
My custom widget preview in unlimited element working well but when i create a new page based on the elementor template in my custom post type, i don’t see my widget.

But what is strange is when i click on edit whith elementor and i save, it’s working.

is clear ? any idea why my custom widget not working immediately ? other unlimited element widgets working well when i use it in template.

Cheers
