Updates to a Bolted Connection changes my material selection

[Vitornis]

I've created my own library of bolts to include multiple material selections for each bolt.  This works fine. But everytime I update my bolted connection, whether i do it manually or automatic it changes my material selection for the bolt to the first material listed in my bolt libaray table.  This is also true for the nuts as well.  Is there something that i have done wrong to make this happen?

Did you map the material field correctly?

humm not sure how can it be done incorrectly?

I have exactly the same problem. A solution to this problem would be appreciated.
