Your Audie should be able to adjust the mould so it's not causing pressure sores. I've had this happen and they mark the spots and file them down a very little at a time until they aren't rubbing.
Absolutely call/email the audie right away, it's their job to make sure the moulds fit right, and if they aren't to correct them, or reorder them (for free).
