New-UDProgress - only circular works?

Only the circular progress seems to be working for me, UD v3.0.2 PU v1.3.1

New-UDProgress -Circular

The below draws nothing…

New-UDProgress -PercentComplete 75

Just trying to display it in a New-UDPaper

If I put it in a modal, it works…

Show-UDModal -Header {
    New-UDTypography -Text "loading page..."
} -Content {

Strange - I was playing with this yesterday on the same version and it was working for me with pretty similar code.
