I got my first x2 clearo last week....after a few refills I notice a inner o ring just under the silver threading.... starting to loop out ,no not the one on mouth piece part...this ring is slightly bigger...impossiable to put back in...without it.she wont vape....so I sat it on top of inner threading and it vapes...but with the other smaller ring it wont seal right...what is this inner ring..?..I even swap them over but the bigger inner one wont seal it either..i sent Jason a ticket....he has no idea...so here I am....ive got ten more ordered.... is it possiable when using my needle tip bottle ive pushed it out..? thanks
