BC application with expired passport

My daughter and wife are applying for British Citizenship.

My daughter's passport has expired. For the question "Do you have a valid passport?", if I answer No, the system doesn't give an option to allow stating that the passport has expired. Instead, it goes in a different direction altogether.

My question is: Is it okay if I answer Yes to this question? I will send/upload her expired passport. I can also add a covering letter to say that we have applied for a new passport (which I plan to do today).

Basically, if I say "No", the system asks: "Reason for not providing your passport". On clicking "Other" and entering "Passport available but expired" it asks:
"Are you able to provide details of your passport using a copy of the information?"
On saying "Yes",
It asks for details, including Expiry date
Entering the old date is not allowed!
Error message: "enter a date that is in the future"

So what do I do?

Both got ILR in Feb 2021. I am a British Citizen by Naturalisation (Tier 2 5-year route).
