Legacy Title missing inserted files when reopen Premiere Pro project

When I insert a file (graphic or picture) into Legacy Title and I open the project in a different computer, it's missing the link for the file. If you try to re-link it when you load the project, you can link everything but these files, even when you locate the files in the hard drive. So I have to open Legacy Title and manually link one by one even when they are linked to the same file.

Is there a way to link them when you are linking all the files when you open the project?

The funny thing is that after opening in a different computer, you try to open the project back in the same computer you created it and you have to re-link them one by one again.

I'm using Premiere Pro 2020 on MacOs Catalina in both computer at home and my office.
