Yeah, that is kinda wierd that you get it no matter what and it affects tanning. Are you using enough lotion when you pump? What about doubling up on the mounting tape, have you tried that yet? I hope this doesn't happen to me once I start using NB lol. I wish I could help you more, but as you can see, I'm not an actual user just yet. Just going by what I read on NB forum.
Hope you figure it out!
