client has invited you to start a 3d project

Hi, I am a freelancer and I am new to cgtrader.

I have already finished a project for a client and it was successful.

the method of working was easy, a notification told me that the client has selected you to do the project, another notification told that the project has been prepaid. and then i saw the project in progress section and started to work on it.

Now there is another client that wants to give me a job but, a notification came up (client has invited you to start a 3d project) and when i clicked on the link a page came up and it was like I my self want to start a project, so is this the new method of hire artist? or it was a mistake from clients?
