coverting nkit to iso, then wbfs

Hello there. I'm having issues using Nkit processing app to convert the file to an .iso. I intend to then convert the .iso to wbfs, which I gather is pretty simple. Here's the message the Nkit processor gives me. This is whether I pick recover to iso or covert to iso. I feel like I'm missing something simple. Anyway, here's the message I'm getting:
