Exception when trying to validate Profile with minValueQuantity/maxValueQuantity

[NilsFa1]

Currently I`m trying to validate a Profile with minValueQuantity/maxValueQuantity elements.

Trying to validate a Ressource using this Profile throws an Exception.

Firely.Fhir.Validation.SchemaResolutionFailedException: Encountered an error while loading schema 'https://fhir.kbv.de/StructureDefinition/KBV_PR_MIO_ULB_Observation_Total_Barthel_Index|1.0.0': Failed to convert ElementDefinition at Observation.value[x]:valueQuantity in profile https://fhir.kbv.de/StructureDefinition/KBV_PR_MIO_ULB_Observation_Total_Barthel_Index: Cannot convert the limit value () to a comparable primitive.
