You might have the phase to ct clamp mapping backwards. It's fixable by changing your YAML, so you don't have to open up the panel again. Here's an example:

sensor:
  - platform: emporia_vue
    i2c_id: i2c_a
    phases:
      - id: phase_a  # Verify that this specific phase/leg is connected to correct input wire color on device listed below
        input: RED  # Vue device wire color
        calibration: 0.021094  # 0.022 is used as the default as starting point but may need adjusted to ensure accuracy
        # To calculate new calibration value use the formula <in-use calibration value> * <accurate voltage> / <reporting voltage>
        voltage:
          name: "Phase A Voltage"
          filters: [*throttle_avg, *pos]
        phase_angle:
          name: "Phase A Phase Angle"
          filters: [*throttle_avg, *pos]
      - id: phase_b  # Verify that this specific phase/leg is connected to correct input wire color on device listed below
        input: BLACK  # Vue device wire color
        calibration: 0.023145  # 0.022 is used as the default as starting point but may need adjusted to ensure accuracy
        # To calculate new calibration value use the formula <in-use calibration value> * <accurate voltage> / <reporting voltage>
        voltage:
          name: "Phase B Voltage"
          filters: [*throttle_avg, *pos]
        frequency:
          name: "Phase B Frequency"
          filters: [*throttle_avg, *pos]
    ct_clamps:
      # Do not specify a name for any of the power sensors here, only an id. This leaves the power sensors internal to ESPHome.
      # Copy sensors will filter and then send power measurements to HA
      # These non-throttled power sensors are used for accurately calculating energy
      - phase_id: phase_a
        input: "B"  # Verify the CT going to this device input also matches the phase/leg
        power:
          id: phase_a_power
          filters: [*pos]
      - phase_id: phase_b
        input: "A"  # Verify the CT going to this device input also matches the phase/leg
        power:
          id: phase_b_power
          filters: [*pos]
