Why does Type 4 RTA cause "hyporeninemic" hypoaldosteronism?

Why does Type 4 RTA cause “hyporeninemic” hypoaldosteronism?

Actually It’s opposite: Aldo def or its resistance cause Type 4RTA( Hyperkalemia with acidosis). Take for ex: CKD which is mostly associated with type 4 RTA: there’s volume overload state which suppress RAAS so renin and aldo is low(hypOreninemic HypOaldosteronism)
