If you haven't watched this video (https://youtu.be/L5bD2DMX8BE) yet, it shows how to get the pieces freed up. However, if you end up with any blobs between the leafs and outer or inner shells, you'll still have lots of problems. In Simplify3D you may want to turn on the "coast" option as this tends to reduce stringing and blobbing. You may also need to increase your retraction. If you only have minor blobs or stringing inside, you can sometimes use a feeler gauge or thin shim to snake between the surfaces and free them up.
