Settings screenshots:
On ajax call form is building OK.
The problem is in $form_state->getTriggeringElement(). It returns wrong element and wrong form part is returned in FormAjaxResponseBuilder.php:
// We need to return the part of the form (or some other content) that needs
// to be re-rendered so the browser can update the page with changed
// content. It is up to the #ajax['callback'] function of the element (may
// or may not be a button) that triggered the Ajax request to determine what
// needs to be rendered.
$callback = NULL;
if (($triggering_element = $form_state->getTriggeringElement()) && isset($triggering_element['#ajax']['callback'])) {
$callback = $triggering_element['#ajax']['callback'];
}
Update 1:
If a paragraph translation has already been added, the issue goes away.
Update 2:
Collapse all and Edit all buttons works fine.
