Check the offsets of the graphics. Newly imported graphics will have offsets at 0, 0. They need to be level with the ground, move the sprite up and to the left and then save. Click away, click back and you'll see a black horizontal line in the middle, that is ground level. Move them to the center and above this line.

Are you saying it's a WAD file with unconverted PNG sprites? Be sure to reconvert it.

Or use the PK3 format and keep the file as PNG.
