Fusion keeps renaming file Untitled when opened

[alan.jonesXHXUF]

File is named MST-13-0311, however as soon as I open it, FUsion's working title becomes Untitled, and when I try and export it it retains the Untitled brand. It was fine in version 2 as I have exports of it. Restarting and rebooting both ineffectual, and only affecting this file. All my others seem fine. It's attached in case it helps

@alan.jonesXHXUF If you right click on the file in the data panel, what are the options that you get? I think what you have uploaded is not converted to a Fusion format and that when you click to open it is translating it to Fusion format and giving it to you as a new Fusion file format.

It's a native fusion design. Right click brings the usual options:

As you can see from the original screenshot Fusion knows exactly which file is open, but it refuses t ouse the correct file name!

@alan.jonesXHXUF is it just this one design or any design is doing this? Would it be possible for you to invite me in to this project with the design? raj.kumar.ilanchelian@autodesk.com
