Schema not generated or with errors

Hi there

I just bought the pro version of your plugin as it was working well on one of my website and wanted to extend to others. Since i bought nothing works properly and as I do not seem to get answers by email I am trying here !
My problem as you will see on the link is that if the widget generate the review schema code, it omits the aggregate rating and i therefore get these critical errors : https://search.google.com/test/rich-results/result?id=Vwbcn-73xrut102LKcMDFg
And the same happens to 2 of my other websites. Someone mentioned a conflict with Rankmath but I am using rankmath and thi trustindex plugin on one another website and all is fine.
I would appreciate any help. Thanks
