Why does Pokemon Super Emerald forget Grandpa's skills but can't?

Hello, I'm a dragonfly from the kingdom of pocket stereo, and I'm glad to answer your question. Jade forgot that grandpa was next to Atian Department Store. If you want to put PM first and forget skills, choose "Yes". I don't know what LZ is talking about. It is better to have a picture. Lz, if you need any help, just ask.
