Credit report info not matching

Rmiller123

Hi, I am currently with Credit Karma with a score of 534 (due to a debt relief order that ended September 2021) but have noticed that the same information such as bank accounts, a new credit card that I took out on 1st March with Aqua and 2 bank accounts have not been added to other sites such as Experian and ClearScore so I have had to amend addresses and add accounts manually.  All 3 sites have a different scoring criteria which is confusing. I have also contacted TransUnion to remove a credit card which was for £2500 which is still showing that its active but this should've been written off as it was included in my DRO (and a major factor in my low credit score showing I've utilised 73% of credit) This is not mentioned all in other reports. What can I do to make sure all the correct information is on all 3 main websites?
