can't change testname from upper to lower case

Hello,

I'm running hobbit 4.1.2

We had some externals scripts that were sending status with upper case. Now, it is sending lower case. The problem is that it is still displaying with upper case in the bb pages. Even if I delete the test, or its history, or if I try to rename like TESTNAME to testname, it still re appear in upper case.

Is hobbit keeping somewhere in memory some traces of the testnames that doesn't exists anymore ?

Is there a trick to rename a test from Upper case to lower case ?

Thank you in advance for the help,
