As you know, generating the helix coils and using them are two separate
things. I have only EZNEC version 3, which does not support automatic
helix generation. However, there does not appear to be any reason why
helices cannot be used in EZNEC version 3. That is what I did. I copied
your wires, edited them, and re-input into EZNEC.

That probably explains everything. Version 4, with the helix
generation option, does a geometry check. The geometry of your
coil is unacceptable to Version 4 of EZNEC.

As for the height, you asked for an 8 foot whip. I adjusted my model
until I got to a 10 foot whip.

Actually, you stopped at 11.775 ft., ~12 feet as I stated earlier.
It won't do any good to keep going. The coil you generated is
unacceptable to EZNEC 4.0.

But thanks for your effort. I learned something about EZNEC.
