Your context window is 80 years. You are forgetting plenty before you reach the end of it.
You generally forget things you don't retrieve. It is not really a bug but a way to declutter for efficiency. That's not the same as it not fitting your context window because it was at the beginning.
It's not about not fitting in context window. LLMs also can "forget" the things from their early context window that they do not restate later. It's also a form of decluttering. You can't (and shouldn't) remember (pay attention to) old stuff with the same priority as new, more relevant stuff.
