I have been downloading-uploading my artifacts to migrate from v1 to v2. One particular folder of 4 PNG files seems to correctly down-up/load 4 files but only one file shows up in the v2 repo and only in the Explorer view. I get an error trying to drag drop the file (null pointer exception). Uploading it to a new folder fails. Using a Composer Archive only results in one file being uploaded.

On a lark, I converted the PNG to a JPG and uploaded it successfully. However, from the Composer Explorer, when I try to open the one file that uploads, I get an error that it cannot connect to the Repo but the repo is clearly accessible using other artifacts. Clicking abort results in the external viewer displaying the .png file but the Composer tab indicates anull pointer exception with the details below:
