Remote Desktop Service for connect two more concurrent Remote Desktop Sessions (multiple users) in Windows Server 2019 Essential

I have Windows Server 2019 Essential. I knew this OS support 25 users/50 devices CALs. I have enabled Remote Desktop and User and Group Policy for multiple Remote Desktop sessions. There are working with two concurrent Remote desktop sessions (users). But If I try to connect third Remote Desktop connection with this server, the message said " another user is signed in. if you continue, they'll be disconnected. do you want to sign in anyway.". When I connect this third RDS, first RDS is disconnected.
Remote Desktop disconnects 1st RDP's user when 3rd RDP's user tries to log on the Windows Server 2019 Essentials.

I already done with enable Multiple RDP Sessions like this:
Enable Multiple RDP Sessions
Log into the server using Remote Desktop.
Open the start screen (press the Windows key) and type gpedit.msc and open it
Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Disabled.
Double click Limit number of connections and set the RD Maximum Connections allowed to 999999.

How can I fix these issues?
I want to connect two more concurrent RDS sessions (upto 25 users).

Thank you.
