Resolution Scores in Intelligent Tagging API

When using the Intelligent Tagging API : https://api-eit.refinitiv.com/permid/calais, for both RDF and JSON formats, I can get all instances of a certain entity in the input text, but I can't get the confidence scores for those entities, as I want to filter the edges to only those above certain threshold. Also for the confidencelevel it's in the parent entity which is not specific to each instance and I found that there's a resolution score in the confidence node but is always returned as 0.0.

What is the best way to achieve this?
