How to Fix Duplicate without user-selected canonical

Hi,

Using OJS 3.3.0-14.

We had two journals under single OJS installation. Now we have divided them individually and moved to new domains.

https://journals.xyzdomain.com/journal-1
https://journals.xyzdomain.com/journal-2

Now, we have moved them to

https://journal.newdomain1.com/index.php/journal-1
https://journal.newdomain2.com/index.php/journal-2

I am using this redirection from old domain:

RewriteEngine on # Redirect matching requests to new domain RewriteRule ^index.php/journal-1(.*)$ https://journal.newdomain1.com/index.php/journal-1$1 [L,R=301] RewriteRule ^index.php/journal-2(.*)$ https://journal.newdomain2.com/index.php/journal-2$1 [L,R=301] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php/$1 [QSA,L]

In google search console, it started showing Duplicate without user-selected canonical

Any suggestions to overcome this issue.

Thank You
