For a project, I have to build steps that are "Invoke Klocwork command". Both use the same KW version, but have a different project name and a different build value ; one using the build specification for debug purpose and the other for release.
I also added KW build option that is "--tables-directory" with value "debug" or "release".

If I then save and configure again, for each "Invoke klocwork command" the build option from the other KW step is added.

For instance, here are the two steps : 1 and 2. Each has the build option A and B.

1 2
A B

I save, click configure, it has become

1 2
A B
B A

I save, click configure, it has become
1 2
A B
B A
B A
A B

Etc

When there are too many option, the javascript become unresponsive and the job is no more configurable.
