Thread:Help talk:Timeline format/Erratic display of events

Referring to this timeline project, can anyone suggest why the number of displayed events is always less than the number of selected events?

The query selects 134 pages with properly formatted dates (they all use the same template and form) but the number actually displayed is ALWAYS less than the number selected. I have tried various values for 'limit' - both 134 and higher; I have also tried reversing sort order and using all the available values for 'timelineposition' - and none at all. All such changes produce different sub-sets of the query selection actually displayed on the timeline but in an unpredictable (to me anyway) fashion.

I have also ruled out page caching or a Mediawiki jobs queue backlog. I really must get this fixed in order to move forward at all with this format.

Any help much appreciated
