I am formatting a facing-page translation using
reledpar and I am seeing occasional (apparently random) extra blank lines in mid-paragraph where there is no break in the source text. You can see this in the example at line 15 on the left-hand page and between 12R and 13R on the right-hand page.
(edit) This is the output of
\showputput around the word "Ybor" towards the end of line 12R on the right-hand side.

There is also a problem in that there is an extra blank line after the first line of every section (on both sides), although this looks like less than one
Before I start stripping everything back to the bare metal for an MWE, has anyone seen this before, or got pointers to where I might start looking?
