Probably in **block_id** here we need to replace block_id with post_id ``` PostGridDataProvider blog_post_listing_data_source block_id id Magento_Ui/js/grid/provider ```

Yes, It has fixed the issue. In below file. `adminhtml/ui_component/blog_post_listing.xml` replace **block_id** with **post_id** and it works.

I have addressed it here, https://www.npmjs.com/package/ng-i18next-extended will raise a pr in ng-i18next as well if someone is maintaining it
