A transaction can get dropped and replaced when a newly created transaction with the same FROM account nonce is accepted and confirmed by the network. And because it has the same account nonce as the previous transaction, it replaces the previous txhash.
Common reasons a replacement transaction is broadcasted :
1. The earlier transaction had a low gas price which would take a very long time to confirm, so a second transaction with a higher gas price was created to replace it
2. The Ethereum Node that the wallet/service connected to was not fully synced, and an incorrect nonce was used
3. User-initiated to replace or cancel a pending transaction
A transaction can be {Dropped} or {Dropped & Replaced}. For additional assistance, please contact the sender/transaction creator directly for more information.
This is why your transaction in Dropped & Replaced condition, because you create new one transaction with the same nonce with higher gas than previous transaction. Nothing suspicious, your transaction will be completed... but your previous gas can't be refunded.
Still tokens transaction is pending since two weeks.
