How do I remove blanks in a PowerApp combobox card used in a SharePoint Form?

[pwrappr01]

I am attempting to customize the New List Item form for a SharePoint list. There is a column that performs a lookup on another column in a different list. That column has some blank values in it.

My list currently shows a ton of blanks at the top of the drop-down, which is very frustrating. Is there a way to remove the blanks? The current formula used for the drop-down is as follows:

Choices('Work Tracker'.'User Name')

In this case, you can use the following formula:

   Filter(Choices('Work Tracker'.'User Name'), !IsBlank(Value))

This will return a table of items that do not have blanks.

I hope this is helpful for you.
