Interference Practice Problems Coded Incorrectly

Hi there, while exploring the Interference problem set with a student (Learn > Practice > Intermediate Tactics) we uncovered three problems that were coded incorrectly, including the introduction. Probably a very easy fix since the hint/answers are correct but playing them on the board doesn't output as a 'success' and instead directs the user to 'try again.'
Wow you guys are good. Fixed and working perfectly.
Should be fixed, let me know if there are other issues on Practice.

They are "coded" correctly, but the win condition is something like -500cp in 3 moves. But with Stockfish version changes/upgrades, the eval can change. Thus you could get a position that is " only " -490cp , so the win condition needs to be changed.
