Google business listings has an ability to add events manually or via indexing a page through google search console with a third party provider. Elfsite currently has a few issues that stops google from indexing events. (Non-critical issues)
We should optimize the service that elfsite provides by making the event calender accessible for google crawl bots, which will better advertise events.
It also increases the views to the elfsite widget… may need a bigger subscription plan 
Hi there @user440 and welcome aboard 
Could you please send me a link to the page where your widget is installed and provide a screenshot with the issues you see?
I’ll be happy to look into this for you 
Thank you!
I’ve shared this info with the devs. Currently, the devs are out of the office, so we’ll get back to you on Monday
Hi @user440! We’ve checked things with the devs, and you may not worry at all, since these are warnings, but not issues. I assure you that they do not affect the widgets’ performance by any means.
The thing is that we’ve changed the markup type to Product in order to display your business’ rating (number of stars) in SERP. This type causes warnings (recommendations) from Google tools to fill in the rest of the fields. Unfortunately, we don’t set different markup types for different types of business, thus these fields remain empty.
I’d love to highlight that these warnings do not affect your website’s and widgets’ performance and position in SERP, so you are very welcome to keep using the widget
