cookTime and prepTime Metada are Missing

Hi. I’m using free version of Wp Ultimate Recipe. And i’m getting error from Google Structured Date Testing Tool for these metadatas: cookTime and prepTime.
I’m using that properties in my all recipes and they show up on the pages. But when i try to test page link from Structured Date Testing Tool, they are missing and it gettin.
I tried to remove plugin and reinstall and it didn’t work. Do you suggest anything?
