Short description of error
When, due to library linking, a multiple datablocks have the same name, the drag and drop mechanism from outliner to geometry nodes editor does not take that into account and references the wrong datablock.
Exact steps for others to reproduce the error
Drag and drop objects/collections in the main.blend example file into the open geometry nodes editor.
