Verify Smart contract BSCSCAN

Hello guys, let's see if somebody can help, I have deployed my smart contract correctly without any problems, While deploying asked me to pay twice as usual, the problem here comes when I try to verify the contract. since we have paid twice, this generated two addresses, we been able to verify ONE address but the other one gives this error:

Error! Unable to generate Contract ByteCode and ABI (Expected library(ies) but one or more was not provided)

Found the following ContractName(s) in source code : ...

But we were unable to locate a matching bytecode (err_code_2)
