Silent Hunter 5 Campaign Help please

[mirrorcarp27]

Hi need help with Silent Hunter 5 Campaign I have completed 3 out of 5 missions already listed below but also failed two of them ?

Invasion of Poland Complete
British Supplies Complete
British Coastal Waters Complete


But have two missions that I have failed listed below

Operation Weserubung Failed
Blockade of Germany Failed

How can I get these two missions back that I have failed as these are no longer on my map to request missions how do I reset them so I can play again I don't want to do all 5 missions again only the ones I have failed which is two listed above this game is on Uplay application interface based not from Steam no mods files are being used

What now I can't seem to find where my next missions are I'm stuck no new black & White cross to accept missions ?

Any help would be great also looking forward to the new Submarine game called Uboat on steam coming Q1 2019 looking good

Kind regards

Scott
