Hi @biubiue

I can't reproduce, as your code isn't complete, and there is no test file included. But I believe this is a known issue (duplicate of #730).

Closing for now. If you have further details on #730 you can comment there. Or if you think this is a separate issue, reopen and add sample files and further details.
