Strange Software-Update behaviour...?

I am on Ventura 13.4.1 but want to get all the security updates to get to 13.5.2 (or even 13.6 which I have seen online).

All Software Update shows me is Sonoma 14.0 and Safari :-(

PS. I changed my SMBIOS between checking for updates? might that be an issue? Is there a way of deleting the Software Update cache???

(I remember previously it listed macOS Command Line Utilities, as well as 13.6). I have switched from iMac19,1 to iMacPro1,1 now.

Any ideas?
