Customization to ensure a global flexfield is present only for certain expense types

Hi All,

There was an ask to customize a new field to be present on only certain expense types out of the entire list of expense types. We deployed a Global DFF with LOV consisting of 2 values for expenses with character type attribute, and the 2 values are Domestic, Foreign. This would help the auditors differentiate if the expenses are Domestic/ Foreign through OTBI reporting. 

Using page composer, we personalized the DFF to hide it from certain expense types using EL Expression. However, the DFF is showing inconsistent behavior: where the asterisk mark was initially visible and later after some time the asterisk mark is no longer visible. In addition, blank value is visible in the drop down of the DFF when there are only 2 values configured for the same. Using the EL Expression also does not make the DFF mandatory.
