the [L] is most probably your problem.

from the rewrite docs

'last|L' (last rule)
Stop the rewriting process here and don't apply any more rewrite rules. This corresponds to the Perl last command or the break command in C. Use this flag to prevent the currently rewritten URL from being rewritten further by following rules. For example, use it to rewrite the root-path URL ('/') to a real one, e.g., '/e/www/'.
