My Pixel 3 does a sound when I lock/unlock my phone, even with this option turned off in the setting

[Android Central Question]

I have never turned on the lock/unlock sound, but a few days ago I noticed the sound and the configuration had changed. I changed it back, but the sound continues, even when my phone is on 'do not disturbe' mode.
All the options on the path below are turned off (I couldn't paste the image)
Settings -> Sound -> Advanced

When I disabled the screen locking sounds I get no sounds. I'm not sure why it won't work on yours.
