The situation is the following. Interface ge-0/0/12 is configured as an access port. An access port can only have one vlan assigned to it.
If you need ge-0/0/12 to pass traffic for more than 1 vlan, it needs to be configured as trunk port. In the other hand, if 0/0/12 is supposed to pass only one vlan, you will need to delete the extra vlans from the configuration.
You can send me the output of the following command: > show configuration interface ge-0/0/12
