Astroquery - Splatalogue not working

I am trying to use astroquery to access Splatalogue. Following the example in the documentation, I get an error:

CO1to0 = Splatalogue.query_lines(115.271u.GHz, 115.273u.GHz) >>> CO1to0.pprint(max_width=200)

InconsistentTableError: Number of header columns (1) inconsistent with data columns (2) at data line 13 Header values: [‘’] Data values: [‘’]
