upgrade to version 2.4.0 do not save the methods that I made the change

Hi

I have composite Project =true.

my project is working fine in the 2.3.0. after I upgrade to 2.4.0 version, I open the project. it told me my PropertyTransfer property can't find it. I find the method it points to old method. I made the change to it then click Save button. close readyAPI. then open readyAPI again. the method still point the old one again.
