help needed with subs

when i create a single mission it keeps giving me a porpoise boat no matter what sub i create the mission with. it does this for the last 3 or 4 of the missions i created.

it must be file corruption of some sort but even with no mods at all and a fresh copy of the data folder the missions still show and run with a porpoise sub.

i have created over a dozen missions with no issues so this isnt my first attempt at doing single missions.

can anyone help me correct this? the last time this started happening i think it was because i deleted a mod directly from the JSGME mods folder but found out later it was still enabled at the time so i told JSGME to uninstall the mod and i think not having the mod in the mods folder is what happened to screw up the game.

the last time this happened i had to reinstall the whole game but i was hoping to avoid that if possible.

here is what is shown in the mission file:
