i always cover the bag filter and just burp my bag so it couldn’t be the filter, i don’t see any parts of the bag lifting from my skin and there’s no leakage and i’m going crazy trying to figure out why there’s still a smell coming from my bag. this has happened multiple times and other people have noticed the smell and i can’t tell what im doing wrong or why this keeps happening, what should i do and is this normal
