"GROWPS" causes the point size for "SH 1" to become larger.
This larger point size is still active when "IP" is called,
and the indent (in current ens) of the "IP" call is interpreted
with the larger point size.

Fixes:

  * Call "IP" with an indent in points, not ens.
    (Not so nice, because it doesn't scale if you
    want to globally change the font size.)

-or-

  * Insert an empty "PP" call before the "IP",
    which resets the font size to the default
    text point size.  Calling "PP" is okay in
    your case because you have set "PD" to zero,
    thus it won't mess up the vertical spacing.

-or-

  * Insert ".ps" before the call to "IP".
    (This might not work if you manually change
    the font size within the section header text,
    in which case you could probably use something
    like ".ps \n(PS" or so instead.)
