I thought at the beginning, this is due name duplication of tables in different schemas but it seems not. Also, this seems as a schema option because it happen only in certain schemas. How I can get a consistent names of the casting ?

If tablename exists in search_path then it will not show the schemaname. Its normal behavior.
You can create function something like given below for consistent names and can use it:
CREATE OR REPLACE FUNCTION pg_get_relname(oid) RETURNS text
as
$$
SELECT n.nspname||'.'|| c.relname as "Name" FROM pg_catalog.pg_class c
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind='r' and c.oid=$1
$$ language sql;
