Security settings change when copy PDF

I'm using Adobe Acrobat Pro DC.  I copy PDF docs l receive and then via "Organise Pages" remove any pages l don't need to use and edit data which l then use out onsite via a different device.  When l copy the original PDF the "Security - Group or user names" remain the same, however once l organise pages or edit the newly created PDF the user names change and the doc is only available on the PC it was created on.  I have to manually go to Properties > Security > Edit and add "Everyone".
I'm on the current version of Adobe and have been doing this for a few months however believe this problem only started in January.

If l extract the pages it doesn't seem to be an issue, however l prefer the method of copying the complete file.

Is there a way to ensure all new copy PDF's (including any edits) are available to "everyone"?

Thanks
