[LOGic] DX OR PREFIX TABLE ERROR

[K0DAN]

Hi LOGic group, I'd like some assistance to determine if I worked a rare DX prefix I've been chasing, or have a long-standing prefix table problem?

I recently worked JD1BMH, as he was in my WANTED list as MINAMI TORISHIMA (JD1-M).

My PREFIX TABLE (probably the original that came with LOGic 4, and manually modified over the years) shows some conflicts with MINAMI TORISHIMA (MARCUS ISLAND?), VOLCANO ISLANDS GROUP (OGASAWARA - BONIN ISLAND).

The web page for JD1BMH suggests Ogasawara.

Some of the LOGic users are religious about keeping their Prefix Table current (I try to but, but....)... 

Would someone help me with the reality of the correct Prefix Table, and in so-doing advise if I have worked a new entity to my DXCC lists?

Thanks and 73
