What springs did you use for the mod? Some of the lighter cherry springs have been known to cause problem with clear stems, additionally if you lubed them with a thick mixture, it could be the reason why they're getting stuck. I would say 62g Koreans would be the minimum you would need to avoid all the headache (Though I've heard of people using lighter). If you applied the stickers the correct way then I doubt they would be the problem, there is hardly any material from the stickers in the actual housing components.
