There is an issue in Telescope due to which it doesn't provide an option to move renditions of a file. This is caused by assets that don't have High-Res renditions while Telescope looks for one to move. Trying to move a High-Res rendition in this scenario by selecting the appropriate option in transfer generates the error message:
None of the selected assets include the requested Renditions to move, whereas de-selecting the option generates
Please select at least one rendition. It has been known to occur for Quark & InDesign files.
This issue was fixed in Telescope Standard 2021.2 and it is recommended to upgrade your Telescope version to this or later to fix this issue. If your Telescope installation has customizations or you're an OnDemand customer, please contact your Account Manager or support for help with upgrading.
Once upgraded, the File Transfer option will display other renditions along with High-Res.
