Serialize and Send Transaction Not Working For Custom Programs

[AyberkDe]

Describe the bug
I'm currently using MW to create unsigned transactions, return to frontend, serialize and sign. After signing and sending the transaction I'm getting "Signature Verification Failed" error from the chain.

I'm using serialize function with requiredAllSignatures and verifySignatures parameters as true and getting no error. However, when sending on-chain this error occurs. When I checked the serialized data created for same transaction on web3.js and Solana.Swift library there were some differences in UInt8 array.

To Reproduce
Steps to reproduce the behavior:

1. https://api.magiceden.dev or https://docs.hyperspace.xyz/hype/developer-guide/ can be used to create the NFT transactions.
2. Create the transaction object from the retrieved tx.
3. Partial sign, serialize and send the transaction on chain.
4. See error

Expected behavior
Transaction should go through and be successful on chain.
