track order

Hello
I have 200 odd tracks within a podcast, for some reason a handful are out of track order.
ie 177, 189 appear at the end of the podcast 'album' rather than at the correct track order.
Ive checked the tags and also tried re editing them from subsonic.
Is there a reason this may be happening or any suggestions on how to fix this?
Thanks for any help.
