What should be the value shown for a collapsed custom date range picker?

I'm working on a custom filter for a photo application. If the user wants to search for a photo, they can select from predefined date ranges or input a custom date range. Selecting a custom date range brings up a calendar.

When the user has selected a custom date range, this then collapses the select dropdown.

In the dropdown's collapsed state, should the value of this change from "Custom" to the actual selected date range (example: March 10, 2020 - June 10, 2020), or should it remain to say, "Custom"?
