Describe the problem:
I had not noticed before. I have a very tiny amount of leftover Link but it shows the “average cost per link” as NZ $758.47 ? that is not correct , link never got that high, maybe around $60 USD.

Which exchange/wallet is this regarding?
Dont know, it appears in the Koinly calculation. Cant pinpoint it to any exchange or wallet.
I have gone over the trades I have done with Link and they all look fine.
How did you import data into this wallet?
API and CSV
What have you tried to fix this so far?
Gone over old trades and compared values and transactions, nothing is missing or unaccounted for. It does not make sense as a average cost. All my other Koinly calculations look fine.
