What do I fill in on my BTEC Module grade?

Hi, basically I'm struggling filling out my eductation section on my UCAS application.
I took a BTEC course and there's quite a lot of modules/units. I began to fill in the first one and filled in my Credit Value and the Level but it's asking me for a Grade when I don't have a grade on my certificate.
Obviously I have the overall thing saying I passed but I don't have a Grade for every unit on my certificate, just the overall course and it says it's madantory to to fill it in for completed modules. What the heck do I put in it?

Here's what the sheet looks like: https://sta.sh/02defxwpasjb
And here's part of my certificate: https://sta.sh/0w560knqedx

Did you get a results sheet at any point with a breakdown at all?

Not that I remember. My partners kept all of my certificates and I only had two from college
