I found that'd happen when I was using organic cotton balls, but I noticed it went away with KGD/Japanese cotton.
With organic cotton balls I'd often "prime the wicks" (an expression I've only heard a few times) by dripping on it and simply firing the device without inhaling until the wicks were more or less dry again. After doing this once or twice that weird papery/wood taste goes away.
