See example (zh.wiki has very strict autoconfirmed requirements so you'll probably not have the permission). This doesn't make any sense as the hits number is shown in the details page of each filter, you just can't filter the log for the relevant entries.
Probably caused by tweaks made in https://bugzilla.wikimedia.org/show_bug.cgi?id=33380.
