iCloud passwords on iPhone vs on Windows PC, discrepancy

I have an iPhone 13 with 423 total passwords in Passwords app. Yes, I know I need to clean them up, but for now I have 423 total passwords stored on iCloud Passwords on my iPhone. This includes 12 passkeys and 29 WiFi passwords and 20 shared passwords. On my Windows 11 PC iCloud Passwords app, it's only showing 378 passwords.

If I do the math and subtract the passkeys and wifi passwords it's close at 382. When I search on the PC Passwords, none of the WiFi passwords are there. That I can sort of understand, but not really. I'd still want access to my wifi passwords on my PC. If I look through the passkeys, some of them are there. The ones that have a password as well. Again, I kind of get that. If a passkey is for a specific device I can understand it not showing up on the PC. But that hardly adds up with these numbers... Can someone please tell me what in God's name is going on here? Should the total number of passwords be the same on both devices or should the list on the PC not include certain passwords and if so, what's the criteria? I'm so confused.

BTW I've uninstalled and reinstalled iCloud on the PC, no change. Actually, it wasn't loading any passwords at all and that's I initially had to reinstall.
