BUG: 5.4.0. Clone a cloned TestSuite (clones the first TestSuite)

I wasn't sure where to report bugs but here I go:

Using SoapUI: 5.4.0.

- I have a TestSuite A, with TestCases & TestSteps.
- When I clone this TestSuite A --> I'll have 'TestSuite B'.
- I made some adjustments to TestSuite B. (You can save, just don't close SoapUI) 
- Try to clone TestSuite B, and I'll have a clone of TestSuite A again.

Only when I fully exit SoapUI and then clone TestSuite B, I'll have a clone of TestSuite B.


Kind regards
