Oracle index is defined identically to the constraint

I have a problem with Oracle SQL Developer where it keeps telling me my index "Index PK_TBLCASENOTE is defined identically to PK_TBLCASENOTES constraint" whenever I go to the Indexes section of my TBLCASENOTE table.

I found this post in Oracle form , but no one seems to have a solution. This is the DDL for table creation.

CREATE TABLE "DSAC"."TBLCASENOTES" (
    "PRIMARYID" NUMBER(11,0), 
    "CLIENTID" NUMBER(11,0), 
    "INTAKEID" NUMBER(11,0), 
    "AGENCYID" NUMBER, 
    "CREATEDDATE" DATE, 
    "CREATEDBY" VARCHAR2(30 BYTE), 
    "MODIFIEDBY" VARCHAR2(30 BYTE),
