How to handle reissued tokens

[Goldmund]

Describe the problem:

I have an ERC-20 token which I purchased back in 2018 which was reissued to a new contract number in 2020. Koinly is recognizing both the old token and new token, which means it’s showing I have double the amount that I actually have.

Which exchange/wallet is this regarding?
Telcoin is the token - erc20 token

How did you import data into this wallet?
Auto import

What have you tried to fix this so far?
I’ve thought about removing the original token purchases, but that may mess up the tax amount as well.

I had this issued resolved in another thread here:

Token upgrade new contract address

Hi, one of the token I has is upgrading to new contract (let say from TOKEN to TOKENv2), meaning, the old token will be worthless soon, and I will have the exact amount of TOKENv2 as it was in TOKEN. The old contract itself won’t be removed from the blockchain, its permanent in blockchain. How do I handle this situation for tax?
