The first time you open the form to add variables at the observation level in the "Add" panel, all fields display their default values. If you enter, for example, 3 variables with their respective names, betas, vcovs, and means, and then leave this section—regardless of whether you add the observation level to the equation—when you return to the form, the variable number field resets to its default value of 1, but the other fields retain the previously entered values. To ensure consistency, all field values should match the specified number of variables, whether we choose to reset all fields or retain previous entries.
