Hi, I am not the developer (they seem to have abandoned the project), but you might find your answer in here:

It’s not specific to this plugin, it’s a Google thing.

Thank you, @immeemz – we have not abandoned the plugin but we are working to just keep it running for now as we migrate all of its features (plus more) into our flagship plugin Starfish Reviews. We hope to have this completed early next year (2022).
In regards to this reported issue by @jpwpbuffs please refer to the information provided by @immeemz. I will be sure and document this known issue during our feature analysis of Rich Reviews for migration into Starfish Reviews. I believe we may have some opportunities to make improvements to the Google Snippet features specifically. There may be some ways that we can help position your page reviews page to Google that would “hide” these dates from being available.
Please keep an eye out on this plugin page for more details/updates on opportunities to start sharing feature requests, ideas, and general feedback on capturing self-managed “reviews” which we will be calling “testimonials” within Starfish Reviews.
