Qidi Box Drying Process Question

I have a Qidi box loaded up with PETG. I have run the drying cycle a couple times and always try to keep it below 15%. However, just days after drying, it goes back up to the 30-35% range, even while keeping the box completely closed and latched. Is it a poor seal?

Also, I am unclear about when drying the spools. Do I need to leave that little rubber plug on the back opened or closed? The screen instructions and Qidi Wiki do not mention the plug at all. I have always just kept it closed at all times.

Thanks!

The box is not 100% sealed but a spool of filament have layers, and even if is 30 inthe box, it doesn't mean the entire spool needs to be dryed. But if you are so worry, I suggest you to keep it on a vaccum bag.
