OK, more now...
1) check the transmission wavelengths of those filters, AND the
sensitivity of your sensor across all wavelengths.
2) If it "looks like"you should be getting something, then I'd
suspect the "hot-mirror".
3) I would not go looking directly at the sun though those filters
because they eye is still sensitive to UV that it CAN'T "see".
4) Test other known sources of UV with the filters over a lens.
Really appreciate your support I will look into your suggestions tomorrow,,,,,stay tuned.
