DFFs behaving differently

Summary:

Hi Team,

We have created Learning Item DFFs which are being shown in Courses/ Offering & Specialization pages as intended by the design. When we type few letters in these DFFs in Specialization page and user Enter/ tab key, system is showing up the search pop up window from were we can select the value. But when we try to do the same in Course/ offering pages, unable to get the pop up search window and we have to click on drop down button -> search & then to select the value.

Since all these pages are getting the DFFs from same setup as these are Learning Items DFFs, we expect to have same behavior in all the pages, please let me know if any of you have faced this issue and is there any fix for the same.
