Why do test cases use outdated steps or parameters during campaign execution?

[Mikasa]

Hi everyone,
I am currently dealing with an issue in SquashTM related to test cases and it is starting to affect our daily work quite a bit.
I have a large test repository with more than 600 test cases organized into folders with shared steps and parameters. After some recent updates and restructuring, I noticed that certain test cases do not behave as expected during campaign execution. Some of them seem to use outdated parameter values or older versions of shared steps, even though I already updated and saved everything in the repository.
What confuses me is that when I open those same test cases directly in the library, they display the correct and latest content. However, when I run them inside a campaign, they appear to rely on an older version. I tried duplicating test cases and relinking them, but the issue still happens randomly.
This is becoming a serious concern because it affects the reliability of our regression testing and reporting. I am wondering if there is some kind of versioning or caching behavior that I might not fully understand.
Has anyone encountered this situation before or found a way to fix it?
