      Sample Misinterpretation

      Description:
      I am experiencing an intermittent issue where imported frequency response traces are shifted an octave higher than previously measured.

      Steps to Reproduce:
      Set the sample rate to 96 kHz on the output IIR in the setup stage.

      Import traces sourced from Klippel dB Lab 212.620 .txt IR exports.

      Observe the frequency response curve in the program.

      Workaround: Restarting the program and loading the averages directory first seems to resolve the issue temporarily.

      Environment:
      Software Version: 4.3.1.4
      Operating System: Windows 10 (Bootcamp on Apple Intel)
      Trace Source: Klippel dB Lab 212.620 .txt IR exports

      Additional Notes:
      The issue may be linked to setting the sample rate to 96 kHz during setup.
      This behavior is inconsistent and does not occur every time.
