Credentials json question

Hi

I raised this thread before: https://teamcity-support.jetbrains.com/hc/en-us/community/posts/16086494022290-Credentilas-json-and-guids-query

I looked at the file, and it does not make it clear which guids match to which parameters in my project?

In addition, I added one more parameter to my project, but the file did not get updated?

Thanks
