Contributors Summary Macro is inconsistent in OnDemand

The Contributors Summary Macro will not show the correct data in OnDemand.
Possible symptoms are:

• Macro shows contributions from entire space instead of the page
• The amount of comments is inaccurate
• The amount of edits in inaccurate
• Some users are missing from the table entirely
• Reindexing does not change the table to the correct numbers

There is no workaround at the moment.
