remove the bit that overwrite limits for evaluators

[ztq1996]

The line deleted will overwrite the limits set in the metric_dict to the default (0.0, 3.0). This is causing a failure in the smoke test.

Code Quality

• [ ] My code follows the code style of this project
• [ ] I have written unit tests or justified all instances of #pragma: no cover; in the case of a bugfix, a new test that breaks as a result of the bug has been added
• [ ] My code contains relevant comments and necessary documentation for future maintainers; the change is reflected in applicable demos/tutorials (with output cleared!) and added/updated docstrings use the NumPy docstring format
• [ ] Any breaking changes, described above, are accompanied by backwards compatibility and deprecation warnings

That makes sense, I have made corresponding changes
