Reupload screen missing with certain pipeline

Hey there

So reupload is all good when you select it via the new edit properties screen. But when you select it via the thumb list item context menu , nothing appears on screen, as if it failed. Although it has started and is busy. This can be see by just taking the previous mentioned pipeline to change properties , you will then see the page report the model is busy reprocessing.
