Siemens breakers in Cutler-Hammer panel.

I’m finding conflicting info on the net. This was a mock inspection, I failed to look at the back of the panel cover for compatible breaker types. This is on a home that is 13 years old in San Diego county if that helps at all. Anyways, I found siemens breakers installed on a cutler-hammer panel. The breakers were added to service the pool.

I would have called it out since the breakers do not match the panel.
