That changes things significantly, the original certificate clearly shows that there are two RCDs. The new report suggests that there is only one.
I seriously doubt that both RCDs have failed, one failure is rare but possible.
I would contact the person who did the report and ask them which of the two RCDs failed, or if it was both. I would also ask them if they tripped when the test button was pressed.
If you can access the property I'd go there and press the test buttons to see if they trip, this does not guarantee that they will trip in the correct time though.
Seeing that original certificate has made me very suspicious of the new report. I can't say anything for sure but it has set an alarm bell ringing in my head.
