Dear Kaur Albertan,
Thanks for writing back with us.
As per the first screenshot attached, I have noticed there is source field in your column and it looks like you opened the column from the Content type and clicked on the Edit column.
In this situation, I would like to you provide us the URL of the Column Settings via below steps:
Step 1: Open the SharePoint Online List> Settings> List Settings.
Step 2: Scroll down to columns in the List Settings and click on the column name:
Step 3: Copy the URL and paste it here.
Moreover, can you please try the below formula and see whether there is any success?
=if([$Is_x0020_Facility_x0020_Manager_x0020_making_x0020_this_x0020_request_x003F_] == ‘Yes’, ‘true’, ‘false’)
Appreciate your patience and understanding with us. Have a great day!!
Best Regards,
Sophia
