Total Layers in Memory Management is not Accurate?

hi folks
i have come to many problems lately with memory management. and all of that related to total layers count
so lets imagine you create a simple empty file in Figma, it starts with 3 layers!!!
oddly when you add your first text it becomes 4 layers!!
But the funny thing is when you paste another text layer (without any style or so) from another Figma file, it will become 6 layers!!!
whats the logic behind that?
my main concern is that when I’m creating a huge design system with dozen layers and different components, the memory usage and total layers its a little bit high in my opinion.
can someone explain the theory behind this?
