@TS not sure if this is the right / best place but it worked for the Missing Replies thread; when I try to use tags to filter whole swathes of threads disappear from the list.  e.g. if I'm in the SolidWorks user forum, turn on tag filtering and look at When > Creation Date, over 8000 threads are indicated for the year 2016;

I then click on "2016" in the left hand menu expecting to see all threads from that year (for further filtering) however all that then shows is only two threads, with a further mismatch between the creation date filter thinking there are 12 but the month totals only coming to the two visible ones.

I assume this is not expected behaviour?  Cache clearing doesn't seem to change anything.  This seems to affect threads created before July / August 2022 when they seem to filter to more believable numbers on a monthly basis.
