Thanks for reporting https://github.com/NodeBB/NodeBB/commit/cf6eadb91a6d6b543429be64751b6f7d6e4543630 barisusakli committed to NodeBB/NodeBB fix: dont let regular users see other users watched categories
Topics count does not match for home and category layout
Category 1 had 17 topics and I 16 were deleted.
In home page you can still see total count 17.
Delete doesn't actually delete the topics, at the minute, NodeBB will only soft delete a topic. This was how it was originally designed, however, you can follow the progress on hard deleting topics here:
thanks @a_5mith I think you know more about NodeBB issues than I do at this point
