Some Series Grid pages can display wrong header. For example, http://www.isfdb.org/cgi-bin/seriesgrid.cgi?20473 displays "Issue Grid: Astounding/Analog (UK)" in the header div even though the actual series name is "Astounding/Analog". It would appear that the name displayed in the header div is the name of the last loaded sub-series of the displayed super-series.
