It sounds like you loaded the film in the holder backwards, with the emulsion away from the lens, and exposed through the anti-halation dye.

That would cause both of those problems (assuming the dye is red, as it is on some films).

When loading the film holder, hold the film in your right hand with the notches at upper right.
With the holder flap open along the top edge, insert the film fully and close the flap. Then insert the dark side.
