HELP WITH BACK SEAT

Hi all, I"m having serious trouble refirring the back seats of my 2003 Freelander Serengeti 5 door.
I took them out to collect a large item but now I"m having a problem fitting the double seat.
I can get it quite close but not close enough. Is there a specific way to Refit them. Do I hook them on the 2 bars which you have to use the yellow handle to release first or do I fit the front bracket first.
Any help will be appreciated

It’s a simple job I am sure if you take a look you see what you haven’t done correctly

In the words of Haynes.. refit is the reverse of removal

Sorry can't be more help
