Beginner Gardening: Plant identification plus fiddle leaf concern, 3 by Plantladyemmy

Hi everyone.
I’m a beginner plant lady although I have had plants for years I’ve never really known how to care for them.
I have one plant in particular that is labelled as a ctenanthe sp. but I am starting to think it has been mislabelled. I believe it may actually be a Stromanthe Triostar.
I’ve attached a photo of my plant and I would really appreciate your opinions.
I would like to be able to care for it accurately and if it has been mislabelled then perhaps I need to be doing it differently.

Also... my fiddle leaf fig has dimples. It had these when I purchased it from Bunnings in Australia, but I assumed the plant would grow out of them. It’s been at least 9 months now since I brought it home.
It’s winter in Australia right now so I’m scared to put it too close to the window.
It has grown its first 2 leaves in the last month since owning it and the newest leaf is also beginning to dimple.
I’ve just repotted it into a self watering pot.
What am I doing wrong?
