Advice should I change from ICR to IBR to get forgiveness

I am on ICR and have over 300 payments. I have not been eligible for IBR due to the fact that I have consolidated parent plus loan and the financial hardship was not previously removed from IBR I could apply now to IBR because I am desperately waiting for forgiveness and ICR forgiveness seems to be taking forever. However, when I look at my file it does say I have 320 qualifying payments on ICR with 0 remaining payments.
However, when I look at IBR it says I am eligible but have zero qualifying payments on IBR and still have 300 to go. I am not eligible for IBR 2014. Therefore, should I just sit tight? Should I change the IBR although the glitch says I have zero qualifying payments? What do you think is the fastest way to forgiveness? Thanks in advance!
