Olias is right about “drying filament”. Putting a spool in the common dryers and cooking it for 6 hours may even be adding water.
When stating that you dried filament, the best verification is how much did the weight change during drying. With common dryers, at high ambient humidity, they just don’t work - even with the door props that let it exchange air with the surroundings.
But also important, if you are starting with dry filament, a drying session under ideal conditions might not remove much or any additional water. Drying filament is actually a very complex topic with lots of caveats. All of that makes it where any meaningful discussions of drying need to include details since many who think they are drying their filament are actually not drying it and could even be making things worse.
Not in any way saying you dried your filament wrong. Just emphasizing what Olias said about weighing it. It’s the first step to drying filament effectively and eliminating moisture as a possible issue.
