I tried the preamp. Though it did not create any 'issues' but it did not improve the signal on my two suspect channels. "sigh" outside it is lol

It was worth a try. Your tvfool report shows very strong signals, but they might be very weak in the attic because of the Techshield.
Is it possible to find a location in the attic for the antenna so that it doesn't have to aim through the aluminum foil of the Techshield?
Can you make a temporary set up of the antenna outside?
Can you set up your antenna inside and aim it west through a window, no metal screen or lowE glass as test?
It is possible there is some noise interference during the day that you don't have at night, like powerline noise or neon sign noise. VHF is more prone to that kind of noise than UHF. I have one VHF channel that is marginal like yours because of powerline noise.
There have been some problems with the Winegard phasing line wires and even some improper assembly of the antenna by the manufacturer, which would make the antenna a poor performer for your VHF channels.

I just checked my hd7694p and my elements were installed wrong as well. Evidently quality control is lacking.

This is what your FM signals look like. They are not real strong, but an FM trap might help.
A separate more directional VHF antenna coupled with your 7694 just for UHF with a UVSJ might help. The idea is to use a VHF antenna that has more gain not just for the gain but for its increased directivity to improve the SNR of your VHF signals that are almost wiped out by noise from electrical interference.
Is there some electrical device in your home that could be causing interference during the day?
