Custom fields

Hi .. Hello
Much like WpErp , but one questions about Custom field ( near to a presale ).
Found wperp trough other people using this, but found the custom field not working properly
example : add a Checkbox field ( Status ) with 3 option ( A B C ) but when go in “edit this contact” … show my for select only one option C and not the other i create.
Also when show the Contact in the field ( Checkbox) created show all the field in option like:
Status : A, C, D,

Have this problem your custom field plugin? , are possible any tryout of this plugins working ?
thankyou
