Rental Income in primary residence coming up as self-employment

Hi,

I rent out a room in my house and have done so for years.  This year, it is aligning up  the rental income with being self-employed and changing the CPP deductions.  I have double checked that "did you have self-employment, rental, or other income" to make sure the rental property box is the only one checked. What else should I be checking  to fix this?

Thanks
