Multi-site Broadcast not moving Featured Image photos over

We have a multi-site set up and we are using a Broadcast plug-in to share article posts between the three sites. When we broadcast, say, from ksvype.com to northcentral.ksvype.com, the Featured Image is not moving over with the post and is leaving a blank image. As a result, we are needing to go to the original post, download the Featured Image and then Removie the blank Featured Image on the shared site and then Upload the proper Featured Image. Is there something we can do to fix this?
