Soap Wrapper fails with param 'index' error even all testcases finish successfully

[PaddyWD]

My Soap UI wrapper always ends with
Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
but all cases are done successfully
Total TestSuites: 0
Total TestCases: 1 (0 failed)
Total TestSteps: 25
Total Request Assertions: 35
Total Failed Assertions: 0
Total Exported Results: 25

I just have a warning at the end that Ginger can't delete a temp directory
'16:43:51,595 WARN [Tools] Could not delete temporary directory C:\UsersXXXXX'
I have this behavior from 4.5 to now 5.31 beta (just until 5.31 it fails with a null ecxeption error “Object Reference Not Set to an instance of an object.” )

Because of that the loaded suite xml does not get updated and future or follow cases that depend on it fail
