Only un-empty value need the filter, so could we move the filter logic in L350~L351?

@sticnarf: Your PR was out of date, I have automatically updated it for you.

At the same time I will also trigger all tests for you:

/run-all-tests

If the CI test fails, you just re-trigger the test that failed and the bot will merge the PR for you after the CI passes.
