Accounts Homepage - Deduplicate Accounts button/action not available/missing/gone

Hello,

We have the Zoho CRM Enterprise Edition Plan.  Three of us are set up as administrators but none of us can see or find the deduplicate button/action that used to and is supposed to exist at the bottom of the accounts homepage.  Where is it?  How can we perform this action?

This feature is critical.  We will need to merge a large volume of accounts as soon as possible.  Please help!

Thank you,

Ethan
