I can’t peel them properly

There’s no doubt that Stickermule’s stickers and the image quality is amazing and affordable. The same can be said with the batch of the Kiss Cut Stickers I received today. However, there’s a huge issue, it won’t peel properly. The first sticker I tried to peel off of its backing; the whole waterproof protection came clean off. I had to peel the whole backing with the design to just pop the sticker out. Some stickers are easier to peel than others, but too many of them have the same problem. Visually they’re beautiful and I love them. However, I’m worried my customers will have a hard time and potentially ruin their sticker (I almost have). Thank you.
