OK, that did help, at least in my case. The delivered US Metric dataset doesn't include the cell used by that part, "ADOBE", while the NM dataset (that I originally tried) does in the ArchitecturalSymbols.cel file. After selecting a different pattern cell from the US Metric dataset everything worked as expected.
Can you double-check that the ADOBE cell is still available within your current project/dataset?
