When using saved layer presets on different maps, the following must be taken into account:

Saved layer presets are not bound to a map. Only the layer ID must match so that the saved properties of map layers can be adjusted. If complete groups or individual map layers from one map are reused in another, the layer presets can also be used on the other map.

The layer ID of saved map settings can be read out in the layer view of a layer presets in the tooltip.
