They're clearly having quality issues with rushing production to try and keep up with immense demand. I've got a few Lee moulds and only the ones from the last 2 years have issues. The cheap 2 cavity ones and even a damned expensive 6 cavity one i had shipped over from the US, all are worse than the older ones. I'm burnt at this point. I think in future I'll be spending the extra to get reliable moulds from another maker.
