Output Pixels Dimensions Don't Export As Expected

When I specify a pixel width to upscale, the exported file is half (50%) of the entered number. When I use the 1x/2x/4x preset scale changes, the exported file pixel dimensions are correct.

Maybe I’m doing something wrong?
(Also posted in General, sorry)

Steps to reproduce issue:

  1. Crop image
  2. Set width in pixels
  3. Export

Topaz Photo AI [v3.0.2] on [Mac]
AppleM2Pro-MacMini.spx (8.9 MB)

Make sure that if you are exporting JPEG files you are setting the Quality to 100 in the Export Settings.
