Wrong a.m./p.m. convention for noon

[filialpails]

The BG showing the outside of the Aoba Clinc lists the morning opening hours as "AM9:00-AM12:00". From context it seems that "AM12:00" is supposed to refer to noon, but in English noon is written as 12 p.m. while 12 a.m. refers to midnight. I think the whole thing should read like

9 a.m.–12 p.m.
3 p.m.–7 p.m.
Fri & Sat 5 p.m.–7 p.m.
