there is something wrong when you create a ticket and you choose client 1 for this ticket
then go to any project ( for example for client 2 ) and add the ticket to his project it will be added and when you click on the ticket it still shows the client 1 as the client name inside the ticket
**if you assigned a ticket when you created it to a client it should appear in available to his project to be added into them
** if the you didn't assign the ticket to anyone when you created it it can be available to any project till its added to a project**
