Hello,

I tried to generate multiple withdrawal credentials for my validator but the tools is always failing. I need to create them one at a time.

463436 and 463437 have the same withdrawal credential, so they used the same validator start_index.
This is the same as the issue pointed out in #345

[ksheni56]

I got the same error when try to doing this in one run, same withdrawal credentials for my two validators. I had to use one validator ID/index 0 for each run, so I've two bls2exe json which I can upload both, correct?
