Why can I not do a periodic mesh despite identical surfaces?

I have a fairly simple structure that is visally periodic yet Comsol refuses to perform a face copy operation. I have attached the mph file and the imported .stp file. Below is my geometry. I have tried splitting my operation into parts and the surfaces that cannot be copied make no sense to be as they are clearly identical. What's the problem?

I have tried various mesh settings as well as the virtual operation of ignoring edges/vertices that intersect the boundaries to no avail.

Here is another example with an even simpler geometry. I really cannot wrap my head around why this happens
