They are the worst kind of leaks, as it'd be very unlikely that you'd be able to hear the air ingress given the relatively small leak. If a thorough pressing down of the tape all around the bag doesn't fix things, it could be a tiny hole in the bag itself (which is usually very easy to pick up and fix once the infusion's running) but, on such a big part, I don't think I'd want to take a risk. Don't forget to try replacing the tape seal around your entry and exit lines, just in case that's the cause.

This helps keep it positioned and helps to stop the bag wrinkling up when installing the entry/exit tubing. Very rarely do they seem to cause and issue since using this method.
