 ### Changed
 
+- Fixed logic bug in the `TokenVoting` and `AddresslistVoting` implementations that caused the `createProposal` function to emit the unvalidated `_startDate` and `_endDate` input arguments (that both can be zero) in the `ProposalCreated` event instead of the validated ones.
 - Changed the `createProposal` functions in `Multisig` to allow creating proposals when the `_msgSender()` is listed in the current block.
 - Changed the `createProposal` functions in `AddresslistVoting` to allow creating proposals when the `_msgSender()` is listed in the current block.
 - Changed the `createProposal` functions in `TokenVoting` to allow creating proposals when the `_msgSender()` owns more tokens at least `minProposerVotingPower()` tokens in the current block.
