Amazing service and response!! :-)
We've found the problem and have put in a fix. It should take effect within the next 3 hours.
It looks like it's getting confused by the detour you added to the first route in the collection. We'll do some further investigation and see if we can work what's going wrong.
When creating a collection of 4 routes, only two of them seem to be visible.
Only Mon and Wed will show on the map.
Something wrong with the routes? They are all visible as individuel routes...
