I've discovered something this morning that puzzles me, and I can't work out how to google it!

In my organiser file I have this task set up -

--8<---------------cut here---------------start------------->8---
*** TODO end of life care
DEADLINE: <2016-12-30 Fri> SCHEDULED: <2016-08-31 Wed +1d>
:PROPERTIES:
:35:00:    35:00
:BUDGET_WEEK: 35:00
:BUDGET_MONTH: 140:00
:BUDGET_YEAR: 500:00
:Effort:   500:00
:END:
:LOGBOOK:
CLOCK: [2016-08-31 Wed 02:46]--[2016-08-31 Wed 03:47] =>  1:01
CLOCK: [2016-08-31 Wed 02:22]--[2016-08-31 Wed 02:23] =>  0:01
:END:
**** TODO death.org
**** TODO to include 'caring with dignity'
--8<---------------cut here---------------end--------------->8---

And when its displayed in the agenda it shows as a grey line of text
which is different from other surrounding text, see attached screenshot
snippet [fn:1].

However, if I take the subtasks out it displays perfectly normally. So
how can I have it displaying normally but still retain the subtasks
please? Are the subtasks position-dependent? Although in my experiments
they don't seem to be.


Thanks
Sharon.
