Output not showing initials

I use a modified Vancouver style for use within my organisation. The authors’ initials are set to ‘AB’ in the bibliography template but only the first initial shows up in the bibliography. Is this a common problem, and does anyone know how to fix it?

If the initials have been input without a space, Endnote treats them as one “name” and abbreviates it to one initial.  Is that what is happening?

Yes, this looks like it. Thank you.
