Problems with Structured Data - Google doesn´t like: https://schema.org/

Hi, I have implemented structured data with help of google structured data of tassos.gr.
On my website piloten.at it works fine. no problem.
On my website reposee.com I implemented exactly the same, but here I am getting two error messages, both related to "aggregateRating is not a valid type and unknown".
I made the same implementation on both sides, but I am getting different results.

Bad result:
https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fwww.reposee.com%2Fblog%2Fhaustauschferien-in-der-region-kitzbuehel

Good result:
https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fwww.piloten.at%2Fblog%2Ftrondheim-strausberg-wr-neustadt-ost-wenn-traeume-wahr-werden

Seems the difference is that in the bad results, Google doesnt like: https://schema.org/AggregateRating with https

I haven´t changed that, dont know how I could.
What do you think?

Thanks.
