Has anyone else run into this?

We are using QC 11 with I think Patch level 3.

Last night I enabled Versioning for the project.

This morning a couple testers have reported to me that their parameters in their test cases, in the Test Lab, are not being populated correctly when doing a manual test execution.

For example, using the Manual Runner she goes:
Begin Run

Then QC 11 prompts for actual values for her 5 parameters. She updates them and presses OK.

Only some of the updated parameter values appear in the test steps, not all of them. I've duplicated this myself a couple of times.

Any idea what might be going on?

Thanks very much in advance,
