CUE sheet - last song's duration

Question

Question is pretty easy - how CUE file reader, like Foobar, can calculate last song duration?
That's sample:

  TRACK 06 AUDIO
    TITLE "Eternal Darkness"
    PERFORMER "TOBC"

    INDEX 00 43:26:38
    INDEX 01 43:28:38

    INDEX 01 68:44:07

I got several .cue , and Foobar is reading them fine, but the problem is that with the last song it displays "?" inside duration field. I can't move around song neither.
How can I fix it?
Thanks!

Answer 1

I ripped several CDs with EAC and found the "?" as the duration of the last track in foobar2000. I think the reason is that I put a number before the name of the .flac and .cue file to keep order. After removing the number, the duration of the last track is back. Hope this helps.

Answer 2

I found that simply opening and then saving the .cue file caused it to work properly in Foobar. Weird stuff. I add an extra blank line at the end of file for good measure.
