Review not visible (despite is allowed in VM configuration)

[Maurizio67]

Hello, I'm working on a Virtuemart project using VirtueMart 4.0.18 10847 (currently in Joomla 4.2.9).
After enabling the review visible to all and writing a review for one product, the existing review is listed but not visible on the product page.
The behavior is the same whatever I chose as a template.
See the attached image
What can do to fix this?
Thanks in advance
Maurizio
