Crescendos/decrescendos not loading correctly

For some reason whenever I load a piece of mine (usually for large symphony orchestra) I find that a lot of my crescendo/decrescendo markings are for some reasoned shortened or have almost disappeared and I have to go through and manually fix them all. Not sure if anybody else has been having this happen. This started shortly after 4.2 came out...I've been having a lot of minor bugs all over the place since this update came out and I'm not sure why.
