UDT instances seem to break when copied

Inside a UDT, I have a folder of UDT instances. Only the first one updates when that child UDT is changed. After investigating (restarting tags, provider, etc didn't work), I realized that the instances not updated are any that I copied.

The JSON of the instances doesn't seem to indicate there should be a difference between the ones copied and created manually. But repeatedly only the ones created using the "Create a new data type instance" button are updating with the child UDT.

Can anyone else recreate this issue?
I'm currently on 8.3.7
