UVs are outside of the canvas and non editable

The attached video shows this entire process, but:
1) Import .abc or alembic file
2) Change view to half 3D half 2d (3D/2D) To see my UVs while I paint
3) Canvas is strangely blank. Maybe they are outside of the canvas somewhere.
4) Zoom Out 30 times to locate the UVs.
5) UVs are found but bigger than the canvas, outside of the bounds of the canvas, undeditable(not paintable), and the two islands for front and back of the shirt are now overlapping on the sleeve.

How can I fix this?
