You did nothing wrong insofar as flying from one provider's service area to another is automatic, however there is currently an FAA-induced SBAS outage in the CL-650's sim world so WAAS is unavailable. In this scenario you have to fallback to non-LPV minimums, and hence Baro-VNAV. On an approach with both LPV and non-LPV available the selection is made in the ARRIVAL DATA page under APPR MODE. However, it may also require changing approaches completely if SBAS is required.
