OK ! Thank you for your support you effectively did well.
After some test i think i found the solution, i let you decide if it’s a bug or not !
in /wp-admin/edit.php?post_type=tribe_events&page=tribe-common&tab=general in Timezone Settings > Timezone mode if i use “Use the sitewide timezone everywhere” it happen, but if i use “Use the local timezones for each event” the “problem” disappear and the navigation works as intended.
