hard issue, need help, fishing

[Ромас Гаубица]

hi, I have a big problem, I started a mission to catch 13 legendary fish, I caught 13 and in between catching other fish, I caught a masking pike, either something happened or didn't happen, I don't remember, but the pike is no longer available for fishing, the icon on the map shows that the pike is not caught, but the reference book shows that it exists, so I can't complete the mission, what should I do?:(
