The problem is that the output still a Multi-block Dataset, so you have to use a "Merge Block" to eliminate the multi-block structure. Maybe a good idea is to modified the "Extract Block" (or add an option) to eliminate the multi-block structure when only one mesh is selected. You can test this creating a "Wavelet" and a "Disk" then group them using "GroupDataset" and apply the procedure.
