DAM Encode Video creates image renditions with jcr:primaryType=sling:orderedFolder which causes thumbnail to display as folder icon

I am having an issue with all of our videos getting image renditions saved into AEM with a jcr:primaryType of sling:orderedFolder (and sling:resourceType cq/dam/custom-renditions). Other types of image renditions have a jcr:primaryType of nt:file. Because the video image renditions are a sling folder, they do not display correctly (sometimes see a folder icon when the rendition is selected to be used somewhere in AEM).

Is there a bug fix for this? or is there a way to customize the jcr:primaryType?

I believe the DAM Encode Video uses this process to generate its thumbnails:
