Clicking on a Shift in My Shifts causes NotFound Exception

[Kazunekit]

Not sure if something wrong with assignment or if the shift shouldn't be visible in My Shifts at all.
Only issue with Staff Shift, other shifts appear to work okay

Just an info for myself: related to deleted shifts but the need to keep them for the users - add a better way to handle the issue
