Currently, in the Lost Authorized value set up - a lost status can be specific to a branch. So only that branch/es can use that specific lost status. This is super helpful in consortiums. With this new Claims Returned feature, you assign a lost value for your Claims returned, and in the set-up (Authorized Value) it does show that it can be branch-specific, however, this is currently not working as expected. This could be due to this bug https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=24279
