Users may like to customize the predefined templates e.g. in order to insert their address or to translate the template into their own language. This is not possible. It's only possible to create an additional template.
In order to reproduce the bug:
 Start LibreOffice and open template Manager: File > New > Templates
 Select: Tab Documents > folder Business Correspondence > “Moderate” business letter
 Click Edit. The document is opened in read-only mode.
 Click Edit Document. The message, that the document cannot be edited, possibly due to missing access rights, is displayed and you are asked if you want to edit a copy of the document. Expected: Template should be editable.
Proposal in order to fix this bug: If a user profile does not exist and LibreOffice is started the first time, the predefined templates should be copied into the new user profile. Hence the user has the right to modify files in his profile, it should be possible to edit templates.
No problem here.

you are right if you are a user with admin rigths. In this case you modify the template for all(!?) users of your system. On my system, if I work as a user with no admin rights the behaviour is as described in my first description.
I think, the current behavior is correct. If the file is in the installation directory, a user with restricted rights should not be allowed to edit the file. You can get your personal copy on demand, so I see no problem here.

Yes, I agree with that.
