Why do I receive a warning "Missing RM data file" regarding a deleted link set file (.slmx) in R2024b?

I have a Simulink model "testmodel.slx" with linked requirements. Simulink automatically creates a "testmodel~slx.slmx" file. I also have a corresponding test case with a link between the test file and the model.
Now, I wanted to remove the requirement. Therefore, I have deleted all requirements and link files in the Requirements Editor. I also deleted the entire Git repository. But when I run the test case, I get the following warning:

Warning: Missing RM data file: C:\Projects\\testmodel~slx.slmx
The warning refers to a subsystem in the model for which I have created a harness (and linked requirements). I have many test cases for different subsystems. But the warning only occurs when I run test cases of the main model.
When I clone the repository with another name, everything works fine. 
How can I find where this missing artifact is linked?

Persistent memory about a deleted .slmx file may exist in two places:

(a) user-owned preference file with linkset file path mapping:  (source artifact path) -> (linkset file path)

(b) .slreqx-owned list of "dependent linksets".

In case (a), the following commands may help to identify and clean up the outdated mapping in user preferences:

  artifact = which('testmodel.slx')
  [linkFilePath, isDefault] = slreq.getLinkFilePath(artifact)
  slreq.map(artifact, 'clear')
  slreq.map('testmodel', 'clear')

If the above does not help, there's probably an outdated "incoming linkset" record stored in .slreqx - case (b).
