Importing CSV registration file with RO tracking

I created a CSV file that has column headings of:
First name, last name, category, division, power factor, checkin (which I used to put the RO, CRO in its cells), squad number

When I import it to PS2, all shooters appear in the shooters list, located correctly to their assigned squads.

Once I check mark the “RO tracking” as preregistered, All shooters still appear in the shooters list, but when I try to enter scores, the squad is either empty, or only the one marked as RO/CRO appear in all the squads with no other shooter.

Is there a solution or advice what do I do wrong

@Mohamed_SAILOR please email your match export file .psc and your csv file to support@practiscore.com we’ll take a look.
