logicmonitor_collector predefined_config not importing

[gdiersing]

I'm using the command terraform import logicmonitor_collector.my_collector <ID> to import existing collectors. After updating the code to reflect the imported resource, I run terraform plan which shows pending updates on the collectors stating:

+ predefined_config = (known after apply)

I run terraform apply and accept the pending change, which confirms Apply complete! Resources: 0 added, 2 changed, 0 destroyed.

However, when I run terraform plan again expecting nothing I get the same pending update for predefined_config
