The new method added is not saved on test case on exit

Hi, 

I have a project for each functionality. For each project I have at least 3 endpoints (dev, test, uat) and different methods (for dev and test for valid or invalid requests). I've cloned the test suit for test to create the uat one and I've added the right method for that (first I've created it using the clone functionality, secondly I've created it from scratch). I saved the project, I saved all the projects and I exit. Next time login the method used by uat test cases is the same with one used on test which means the save wasn't taken in consideration. 

Any suggestion? It is quite urgent. 

Thank you!
