Learning rate (display) issue

[transwarp829]

Describe the bug
I have set a different learning rate (compared to the default 1e-4) as well as a different value of lr_decay for my training in config.json.

However during training the lr displayed in Tensorboard shows a constant value of 1e-4 at any steps.

To Reproduce
Steps to reproduce the behavior:

Set a different lr or lr_decay, observer the lr log in Tensorboard

Additional context
I wonder if this is a bug in display or the manually set lr and lr_decay is not used after lightning is implemented?
