Steel Support Column with 4x4 buffer

This basement on a 1950-1960s house had multiple (8-10) steel support posts. Some were supporting the beam. The one showed here was under a floor joist and it had a 4x4 and a 1x4 in between the top plate and the joist. It was not fastened to the “buffer” boards. Is this a problem if this is not a bearing beam?
Also, the posts that are supporting the beams were attached using nails instead of lag screws. Thanks for the help.

Nails don’t get it!

And, why is that short post there, if it is not carrying some load?

Thanks for the reply Larry. I don’t know if it is or is not carrying a load and don’t want to speculate on that, it just seems to not be carrying a load because it’s not under a beam - just the floor joist. There are 7 or 8 more of these that are all under beams (those are the ones secured with nails only).

Greg, it is not built well enough to be a point load so I still wonder why it is there.

You got it that nails are unacceptable from post to beam or post to floor? Right?

Yes got it. Thanks again.
