Category talk:Inhabitants by religion

Sorting?
Does anyone know why most categories "Worshipers of ..." are sorted nicely under the name of the deity, not W like Worshipers, but e.g. Category:Worshipers of Diirinka is not? I thought this might be cause by the template "Main", like it is employed in Category:Worshipers of Ghaunadaur, but this is not used in Diirinka and some. Daranios (talk) 19:18, June 28, 2015 (UTC)
