Can you document the steps here Steve? I tried editing a few plans and could not duplicate that issue, so maybe I'm doing something differently than you are.

Edit a V7 file plan in portal. Go to compression and encryption. Sometimes the defaul encryption key is visible, other times if you look at it is shows jlx40..6mp…qZnu9wVJQ==
If you then save the plan it changes the key apparently.

I'm currently speaking to support about this, but I think the solution is not to show the password until the fix is in place.

I have been avoiding looking at the keys for that reason, but the prefilled pw managed to get saved in a plan forcing a full backup to occur. Could be that someone on the team looked at it, not realizing the implications.
I am just glad that it throws a notification that the encryption key has been changed. Otherwise we’d never know until a restore didn’t work. Would be looking for another job.

according to the latest tests by support even if you show the password, and then save the plan the password doesn't change on the plan itself. They were unable to duplicate the scenario you're running into where it actually changes. Are you sure you didn't modify the password in any way even if it was retyping the one that it was showing incorrectly? I think they want to see the logs for that particular plan execution where it backed up everything again, so I would send those along on the open support case.

I will send the logs to the open ticket. Thanks for your help.

So it turns out that the prefilled encryption key is not causing the issue, the original encryption key was wrong so when I put in the right one, it said it had changed and would do a new full.
Looking for a way to tell which other plans have the wrong encryptiuon key . In legacy, I would simply download a small file using Cloudberry Explorer and if the Encrtyption keyis correct, the download works.
In V7 however, all I see in CB Explorer is a lengthy string for each plan. Is there any way to display the string associated with each plan?

Figured out a way - The CBB_Report Folder has the same strings associated with the plans so by loolking at the plan run report I can match them up.

Thanks for all the updates Steve.
