Thanks! Will look into it

Sorry it took so long—I thought I need linux to reproduce, when in fact it was platform-independent. Should be fixed now

I apologize for not providing more context earlier. The result I obtained is from running this code on Arch Linux, and it's possible that this issue may not be reproducible on other platforms. I'm not certain about it. If you need any further information, please feel free to contact me anytime.
