Files have custom access after Time Machine migration to Mac mini

I recently bought a new Mini Mac (M4) Tahoe 26.6.2 and transferred files to it from an old Mac via a Time Machine Back Up. All seemed fine, but folders and basic documents such as pages and numbers files that I need to work on only have 'custom access' in the 'sharing and permissions' so short of copying and pasting everything into new documents it is all useless to me. How can I change this ?

Mac mini, macOS 10.15

If you migrated to the new Mac mini during the initial setup using your same User Account...?

Then everything should be contained with-in that one Users Account.

If you setup the new Mac mini first using a different Account and then migrated your old User Account ...?

You will end up with two different User Accounts that can only Share data.

At this point you have 2 options if you have two User Accounts.

1) Wipe the new Mac mini and Migrate your old User during the setup.

2) Continue to live with Sharing User files between the two User Accounts.
