Hi @cza ,
Thanks for reporting the issue, this was reported before in WIP: Filters don't work on query loops with an offset
The count is not right when offset value exists in Query settings.
However, for your second question, if you are filtering “Test” category, the result is empty which is expected. This is because you are querying all posts where category is “Test” + offset 1, and your entire website only has 1 post with “Test” category, the offset 1 causing no result. Hope this explanation makes sense.
Regards,
Jenn
