Schema markup in SERP in s ome languages but not in English. Any suggestions?

[lcourse]

I have schema markup on a category page and on a product page on a website in 10 languages.

Product page markup is showing in google SERP in all languages (both star rating, number of votes).

Category page markup is showing very inconsistently. For English google SERP do not pick it up at all.

For Spanish and German they are showing completely in SERP (votes, minimum price), for other languages, just part of makrup (minimum price) is shown in google SERP.

In rich snippet tool they show up correctly in all languages.

Any suggestion what can be done to get schema of category page picked up more consistently?

Any experience of other markup formats than schema being picked up better?

Thanks

Having semantic markup doesn't guarantee that Google will display rich snippets in the SERPs, it's up to Google to decide whether rich snippets would be useful or not. If it is showing correctly in the testing tool, then the code is fine, it's just up to Google how to display your content. Schema.org is probably the best semantic markup to go with at this point, and it's supported by all the major search engines.
