Thank you Tom.
We were unaware of the bug within G.
Guess that answers it.
So, a follow up question, if I may? We, and I have seen others, have submitted multiple versions of the disavow file. Unless we keep absolute track of these links and domains there is no way to know if the links are indexed and hurting us?
If we have a domain that has been disavowed, but still shows in GWT, how can we tell if it is in index for our site?
Thanks again.
