[otrs] Criticality <-> Impact <-> Priority Matrix empty

Hello, today I found that in our OTRS 3.3.7 with ITSM I am unable to create new Services, because we dont have any Criticality set. Funny thing is that when I go to Criticality <-> Impact <-> Priority Matrix I am presented with this: http://s17.postimg.org/fevcai6jz/image.jpg I found this really strange since we had few test services defined in the pasted I am 100% sure that matrix was available. Any idea what could cause this and how to fix it? Thanks
