As I’m new to Typescript I am unaware of the prevalence of import * as xyz however you were right, importing the moddle in that manner was the problem. The only change I had to make was for the import to read as follows:
import camundaModdleDescriptor from 'camunda-bpmn-moddle/resources/camunda.json';
With that change the property groups seems to be loading properly in the panel so thanks for the help! The CSS still seems to be off however I feel much more confident in handling that issue.
Thanks once again,
Paul
