Is there a limit for how many Stored Named Attributes you can have in a geometry node or receive in a material?

Clik here to view.

I've been using Stored Named Attributes on this geo node to pass the values to the shader editor - and I've noticed some attributes on the shader have stopped receiving info -, and when I tried "muting" a few Stored Named Attributes on the geo node, some others started working again.

There are no competing attributes or something like that, I've more than triple checked.

I looked up how many attributes I have and they are 22. I never thought there was a limit. Is it like 20?

Or is this a glitch maybe? I'm on 4.0.2.
