There seems to a problem with Template:InfoboxSubsectorSimple. If you look at the Special Page Wanted Templates, the top one on the list is Template:Alg, if you look at the list of pages asking for it, they all seem to be pages using the Template:InfoboxSubsectorSimple. All the pages have an extra '}' at the beginning of the page, which suggests something broken in the Template.
Template:InfoboxSubsector doesn't seem to have the problem, as most subsector pages look OK.
I don't know enough about how the templates work to pin it down exactly, but there is one possibly suspect difference between the Template:InfoboxSubsectorSimple and Template:InfoboxSubsector. The first one says that the 'alg' code defines the colour of the bar and does something about categories. The second one only refers to the colour of the bar. I wonder if that points to where in the template definition the problem is? 188.8.131.52 07:02, 18 June 2015 (EDT)
