3MF Export Options Unavailable?

[diff-arch]

Hi,

When I try to export a .3mf file the options aren’t available any more?

The options dialogue used to pop up every time I exported a file.

Fixed by entering ResetMessageBoxes as suggested by @wim here.
I must have checked “Always use these settings. Do not show this dialogue again.” at a previous export.
