Listing is 100%, but not completing to go live

I'm so confused ... please do help! 

I have prepared and submitted my listing. It says "100% complete - we're reviewing your property".

Then goes to the blue page stating You're Nearly There. On this page, it doesn't progress beyond the stage "Laying out your living room".

It appears I'm unable to amend the listing in this stage, and yet the listing isn't going live.

Any guidance on what I should be doing next would be hugely welcome. Thank you all.
