Not sure if I can shed any light but let me tell you of my problem.
I can't get my PDWA light to go off either and I have done as you did on
front and rear brakes separately. I will have to investigate further, but I
would suggest that you re-bleed your brakes starting with the rear right
(assuming you have a LHD) and working to the front left. Give several pumps
after the fluid appears to have no bubbles because you can be surprised
sometimes. Also, make sure the rear of the reservoir is full not just the
front as air can get in that way too (I am assuming too that you have the
same kind of large cap reservoir as I do on my '75).
Then try the brakes again.
If it works, you are one step ahead of me!!
