[BUG] Signing Stall, Some Proposal batches not being signed

[shekohex]

Describe the bug

Currently the Signing is not 100% working, when sent 3 Anchor Update Proposals, each targeting different chain, result in 3 different batches, only 2 out of the 3 got signed. I tried this 3 times and always a random batch got left without being signed.

To Reproduce Steps to reproduce the behavior:

1. Go to Development dApp
2. Do a Deposit on one of the 4 Networks (Tangle, Athena, Hermes, and Demeter)
3. You will see 3 Proposals got added on chain
4. Only Two of them gets signed.
