I have bought MANY sticker sheets from these guys for the past couple years or so. There's about a 50/50 chance of getting a sticker sheet where they aren't cut deep enough, aren't cut all the way around, or are double cut in a way that creates extra trim lines that can get stuck to the bottom of the sticker. Usually it's just with some of the stickers on the sheet. In fact, most sheets have at least some of these issues. Bending the sheet this way or the other doesn't change any of this. So yes, it is definitely a problem. Another issue I have seen many times recently is poorly centered (relative to the cut) faction insignias, which can be very unsightly and requires a lot of cutting to fix.
