Oracle index is defined identically to constraint

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

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

The issue is because Oracle automatically creates an index for a primary key if no index already exists. The collision is because of attempting to create an index on the same column, though slightly different name.

My last place set constraints separately from the table creation, which meant that you'd use the following steps:

1. Create table (no constraints, incl. primary key)
2. Create index(es)
3. Apply constraints
