Cannot tie swung note

[Tim Mariott]

In the attached "When I'm sixty-four" which I am preparing for choir learning files, at measures 9-10 and 17-18 in the Tenor and Bass lines, the arranger has specified swung notes tied to a crochet in the next measure. No way will Composer allow me to tie these notes: it tells me that the notes are not the same pitch.

Later in this arrangement the same pattern of notes occurs but this time without the "swing" and now the same notes can be tied - measures 42-43 and 50-51.

Also I note that swung notes can be tied to a succeeding note if they are in the same measure, e.g. at measure 7 and many other times.

So what is blocking the ties in measures 9-10 and 17-18 and is there a work around? I don't really want to have "unswing" these notes as it is an important part of this arrangement.

Thanks
Tim
