Woow! Am not trying to scare u but this is what I think I know. I could be wrong anyway. I think this mistake is something u should notify them asap. These are two categories ie "Spouse living inside Canada" which is INLAND and the other OUTLAND. These two categories have different processing times for 2016 apps, not sure about the new applicants and I think they would be expecting to see some document backing up her stay in Canada which u don't have and didn't include.
When did u submit ur app? Pls try and correct this error to avoid much delays. CIC usually returns app with mistkes after the file has spent time in thier custody and u have to start again.
So sorry about that.
Submitted September 18th, 2017, so I doubt they have opened it yet.
