The version of this plugin that will be included in 8.5.x resolves this issue by omitting some of the troublesome metadata fields. Because the changes go beyond the team plugin, we can't update the openntf version to do the same thing.
The shipping version of this function also has a much improved UI, and a number of changes - one in particular that should be noted is that images are stored in the same fashion as files are, while this early version stores them as DXL. This is something to be prepared for when upgrading to the next version of Designer.
