Excessive number of values

At the moment average (!) number of values per item is 23, while maximum is 832, 632 (see query). That is way too much excessive causing that it is hard to work with most populated items (thus reducing its accesability). That is very bad. Any idea how to solve that?--Jklamo (talk) 19:35, 15 February 2018 (UTC)
