Context based DFF created for the supplier contact not showing on the Supplier Contact page

We have created a context-based DFF in Manage Trading Community Person Descriptive Flexfields, but it is not being displayed on the Contacts screen.

We created two contexts "Primary Contact" and "Shareholder" and added a "Percentage" segment under the Shareholder context. After deploying the DFF, the context-based DFF is still not visible on the Contacts page.
