Advanced Search Using DropDown Values not working

As the subject describes, I have several DropDown Fields added in the Accounts Advanced Search that return no records when used. For example:

  1. If I use >Search Accounts>Advanced using a partial name results are returned correctly.
  2. However, if I add any DropDown in the filter No results are returned

See below for screenshots.

Can someone direct me to where I am failing to understand this function. And, hopefully resolve this?

Thank You for your help…

There is suitecrm.log file in CRM root. Do you see any FATAL error for query in that.

Also confirm if your records do have an Assigned To field filled correctly.
