I wonder if she is getting too much day sleep and is therefore not tired enough for a good night sleep.
Her morning A times are very short, more of a 4-5month olds A times and I wonder if that first Nap is being taked on to her night sleep.
How tired is she when you PD at 9.30/10am? I think you could push this nap time out gradually 30mins (10mins at a time every few days) and cap the nap or the other at 1.5 hours. This would give you a good 3.5hours day sleep and hopefully she will be more tired from the increased A time to sleep at night.
ie
WU 7.30am (eventually it will be 7 with a better sleep)
Nap 10.00-11.30
Nap 2.00-4.00
BT 7pm
Her nights are very short with the long NW, and I do think maybe she is catching up during the day and you have a bit of a cycle...what do you think?
