This seems to be a problem in the MusicXML export from Sibelius. "wavy-lines" are being added to the trills in the MusicXML data, such as:

                                <notations>
                                        <ornaments>
                                                <trill-mark default-y='20'/>
                                                <wavy-line type='start' number='1'/>
                                        </ornaments>
                                </notations>

Maybe there is a way to fix this in Sibelius, but it is an invisible problem, so maybe difficult to fix. It will be easiest to fix in Humdrum by deleting the second T or t on the trill note.

There is a second problem in this example: the double-flat is not present in the MusicXML file, and hence not in the Humdrum file. This seems to be a limitation of Sibelius MusicXML export, so it will have to be added by hand in the Humdrum file. To do this will be easy: Change the T marker for a trill on the first note into a t. T means a whole-tone trill (so it would to go E-flat, and t means a half-tone trill (so the trill would be to E-double-flat, and the double flat would be added above the trill in the notation automatically).
