inconsistencies displaying all metrics despite same parameters

Having an issue running tests where certain metrics are sometimes captured for pages (my biggest issue seems to be DOM elements), and sometimes not, despite the fact that all settings seem to be the same. Trying to isolate the cause of this. Always use Dulles and IE11. Sometimes there is a DOM Elements column in my results, sometimes it’s absent. I can certainly provide more information if necessary. Couldn’t find anything else in the forums that covered this, so I’m hoping there might be a single easily isolated variable that I’m not aware of.

Could you post your test URLs?
