Is the stock printed 4 over 4?
Is the spot U/V also 4 over 4?

We only know what you tell us about the job.

Why did you need to leave it for 3 more days after spot uv? Is the gas ghosting coming from print on other side or print trying to come through the UV?

If its chemical ghost, you need to get air into it before it happens.Not sure what your job looks like so . Lots of time with a chemical ghost if this is what you have, you can lay a varnish over it, air it within a hour or so very gently......send her back for spot, air again. The key is air here.
