Error of multi-metric and multi-channel image registration

[jslalu]

I had a pair of images with 12 channels for bspline registration with a combined metric of "AdvancedNormalizedCorrelation" and "TransformBendingEnergyPenalty", but the following error occurred.

itk::ExceptionObject (00000015B8FCC430)
Location: "ElastixTemplate - Run()"
File: D:\a\im\build\cp310-cp310-win_amd64_deps\elx-src\Components\Registrations\MultiMetricMultiResolutionRegistration\itkMultiMetricMultiResolutionImageRegistrationMethod.hxx
Line: 523
Description: ITK ERROR: MultiMetricMultiResolutionRegistration(00000153BD5E2800): The number of fixed image pyramids should be >= the number of fixed images

Then I repeated the image pyramids 12 times, but another error occurred.

These two errors are contradictory. Is there a solution for this case?
