Error | svnauthz: E220003: Section appears more than once in the authz file: [groups]

Hello,

After the change from Subversion 1.8 to 1.14 on my server
the access rights definitions in the svn_access_file
no longer work.
The following error message appears:
[authz_svn:error] Failed to load the mod_authz_svn config: Error while
parsing config file: '/opt/csvn/release/data/conf/svn_access_file':
svnauthz: E220003: Section appears more than once in the authz file:
[groups]

Is it no longer possible to define groups more than once
per repository in the acccess file? I find this style
more clearly organised, than to separate all groups
of the repos and the corresponding access rights
separate.

Is there a possibility to stay in the old format (Subvesion 1.8)?

Here is an extract from the svn_access_file file.

Thanks for your help,
