TariqHussain Thank you very much for the suggestion.
Tried to use API V1 using the following queries
/restapi/vc/boards/id/board_ID/messages/count /restapi/vc/categories/id/category_ID/posts/count
If API V2 call returned 0 for board in question, API V1 call returned the same value as native CategoryPage.NodeList component showing that something is inside (although that board is empty).
API V1 call returned the same value as API V2 call when applied to categories, but unfortunately in both cases the value didn't match the native component.
If the native components show there is something inside when its empty actually, it is due to cache or indexing issue.
You need to clear cache and check, if this doesn't solve the issue, open a ticket with lithium support for clear the cache and re-index the board data.
Thank you very much for your suggestion, we will try to approach lithium's support.
Unfortunately, clearing cache didn't solve the issue.
