Missing lintels?

Is this actually a problem? All the openings in this foundation seem to be missing lintels. The blocks are closed. Is there a site explaining this application if correct?

Thanks

Those are pre-cast lintels.

I’ll see if I can find a pic…

Here’s a pre-cast lintel:

Do not see a cross section
How are they made?

Not sure, they are slightly lighter in color than the surrounding block and all look good with the exception of the third photo. (minor deterioration)

What I see is what they call a Bondbeam Block or knockout bondbeam.
