The Scope dropdown is not showing the filter I want to base my Cost Tracker project on

When creating a Cost Tracker project, I can see a list of filters in the Scope dropdown, but the filter I want to choose is not listed

The Scope dropdown is showing a maximum of 50 filters that the user has access to in Jira (own or shared filters)

The filters listed at the top of the dropdown list are the one's that are marked as favorites by the user. They are listed in alphabetical order.
If the user has less then 50 favorites, the Scope dropdown list is populated with "non-favorite" filters, also in alphabetical order. 
It is also possible to use the search functionality in the Scope field, to find filters outside of the 50 returned one's or to avoid having to scroll through the dropdown list.
