Check the Johto region restriction
Only Johto League members count toward the member threshold. Kanto members do not substitute for them. Challenges that specify Johto companions must also be completed with Johto companions.
Check tracking and the single-run status target separately
Use Johto companions to fill the relevant tracking gauge in Ecruteak City. Check the current in-game tracking instructions for how the gauge increases and any difficulty requirements.
Complete the status target within one run; do not add progress from separate runs. The objective counts companions affected by the specified status, rather than ordinary defeats.
Even after completing the status target, finish the tracking gauge and confirm that your League has at least 32 Johto members.
