Service Desk 7.5 Cannot close incident with No SLAs on Process

Hi,

First time posting so apologies if I haven't given enough information or I am asking in the wrong location.

We are currently running Service Desk 7.5 and we have a number of incidents which we are unable to close and are still appearing in our queues.

It appears that there are no SLAs on ticket and the Current Assigments are blank, even though this was filled in.

Due to the state that the ticket is now in i cannot edit or reopen it.

Clik here to view.

If you need any more information then please let me know?

Thanks

Luke
