iCloud Passwords for some sites in Edge/Windows are correct but get rejected

Hello,

I'm using the iCloud Password Manager in Windows 10 and 11, Edge Browser.

Many of the passwords work fine.

Some do not, even though they work fine when signing on an iPad or Mac.

The password manager fills in the ID and password but when I submit I get 'incorrect ID or password'.

When I manually type that same information, the entry works.

I tried deleting and re-entering entries.

I tried deleting the extension and re-adding.

Any other ideas to try?

Thanks!
