Hello,

We have confirmed this concern on our Test Site and there the Tooltip is working accordingly: https://snipboard.io/aty0u3.jpg

So, this isn’t a Theme end concern as this clears the doubt.

On your Site, please once navigate to the Dashboard > Theme Settings > Single Product > Reviews > there check if you have written the Maximum upload file size or not: https://snipboard.io/0O3SqU.jpg

If yes and still facing issues then could you please once try deactivating all the third party Plugins on your Site, remaining the Theme required ones activated. If the issue gets resolved, then reactivate them one by one to see which Plugin is causing the issue. If this doesn’t work for you then once also, try to activate the Parent Theme on your Site if you are using Child Theme on your Site.

If somehow the issue still persists, then please take complete Backup of your Site first, then provide us the WP-ADMIN Login details of your Site in the Private Content field along with the permission to completely debug your Site which includes deactivating all the third party Plugins and removal of on-Site Customization changes too, so that we can thoroughly check this issue on your Site and assist you accordingly.

Best Regards
