The words on OpenCycleMap are because OCM does not update it's data as frequently, so it is still using the node with the name trossach wandelgebied. Someone reverted this change 3 or more days ago. OCM will eventually refresh its data and all will be well again. It's important to look at the underlying OSM data (eg select data view) rather than any given rendered view which may be using data from minutes, hours or days ago.
