Unable to set VLAN membership for VLAN ( 1675 ), Change the port to general mode, and then try again

[Akshay_gm]

There is aldready a VLAN set in the switch which has all the ports assigned to it & i want to creat another VLAN. when i try to assign ports to it, It shows "Unable to set VLAN membership for VLAN ( 10 )"

and when i tryed to remove the ports from old VLAN it is showing Unable to set VLAN membership for VLAN ( 1675 ), Change the port to general mode, and then try again.

what to do 

i have attached some images for refrence.

Consider to define these ports as tagged - does not make lot of sense (read: none!) having all ports on VLAN 1, 10, and 1675 defined as untagged.
