Change to last month's report in Credit Club

onthego

I went back into my most recent credit club report, and noticed it had my current address listed as somewhere I've not lived for ages. Went back to the PDF of it I saved previously, it had my correct current address and the other address was in the history where it should be. Saved the PDF again from the online one, it came out with the wrong current address. Went to report an issue on this item, it told me to go to settings to make any updates. Went to settings, checked my current address was correct which it was, saved nothing, didn't even go into edit mode. Went back to most recent credit report online, now has correct address again. Saved another PDF. To prove I'm not mad, I have 3 PDFs, all saying they are of the same report, two with the correct current address, one with the wrong current address.
I am really torn as to whether there is any point using this system, and also worried that actual financial institutions making decisions about me might be getting weird randomly changing information, often with errors in, like I see on MSE.
