Help wanted: confirm source code issue! Unable to verify source - Invalid Address format for Library_1 Name

Dear All, I am looking to copy this smart contract https://bscscan.com/address/0x1F921D5c52De0590e66E3659460EC9E2574ef09a , but when I deploy and try to verify the source code on bscscan I run into this issue:

Error! Unable to verify source code
err_code_1a Occured: Error! Invalid Address format ( 4c47a2dac52b51ec56ca845ffc5e15cfcd3de54 ) for Library_1 Name ( IterableMapping )

Looking for someone to help me solve this issue. Bounty: 0,1 BNB. Telegram: @Moncheryy
