Hello @elhacene,
thank you for sharing your profile. I can see only 569 out of your 749 reviews are public, either because they were rejected at a later point in time and/or some of the places were deleted. As a first step, I suggest to identify which are those hidden reviews. In How to find your hidden reviews you find a method how to do so.
But not only that. Out of your 5,769 photos and videos, only 5,160 went public, as you can see in this screenshot:
If a photos or videos are attached to a review and only one of is not published, the entire review is also rejected. So after identifying hidden reviews, the first step should be to delete any attached media.
This could happen because of reviews being rejected at a later time.
Hope this helps. Let us know, if you have questions.
