Yes, I can see all the custom labels in the elevation data view now
Thanks for the quick resolution!
We've found the problem and put in a fix, so it should be OK now.
That does sound like a bug. We'll have a look into it and post back when we have an update. Thanks for flagging this up.
In a route I created I have added 11 custom labels, they are all visible in the map view and in the elevation chart view, but only 5 of them are visible in the elevation data view (and only these 5 are exported in the csv when you download rout profile data)
