Q: missing accounts after sleep macbook pro

I have a macbook pro. Recently changed the motherboard (old school lingo). Now when I close the lid without logging off my account, when it wakes up to the login screen, the other accounts do not show up (I have accounts for my kids). It does not have the back button next to the logged in account to go back to show all the accounts on the computer. I either have to log off of my account before putting the mac to sleep or reboot after wake up to see all the accounts.

I did not have an issue prior to having the motherboard switched out. I've looked over my settings and cannot find anything that would contribute to this issue.

Any help would be appreciated.
