***Farming / Staked LP Tokens are LP tokens that you deposit into a smart contract such as a Rewards Pool or Vault to earn additional awards apart from fees

The reason you might be seeing it is that we track your mints and burns of your LP tokens.
If you transferred LP tokens in/out, we don't count them as debits or credits. This is because if you sent it to a farm, we still want to track your positions.

Consequently, some protocols take a commission off your LP tokens, and thus it might show that you have some but in reality, you don't have it. There are different possibilities and we can only guess at what is there. The best thing to do is to check the transaction history in More Details and see exactly what happened.
