Same Lock Ids is normal ?

Hey,

Today i got lock without entering instance at ToC 25 don't know how is happened but i'm saying as it was, aslo ppl can't sum me in instance but i have same id. After that I noticed that i have same id for all instances. Id is -2147483648. Is this normal ? :/

There is a display issue regarding the ID itself, but they are working properly. You probably got saved and forgot about it
