Form select (dropdown). Not showing dynamic values and static values not deleting

Done this loads of times and never had a problem but now this wont work.
Have another select on this page which works so that just adds to my confusion
Basically i have an update form on which i want to add a select (dropdown) form control.
I have created a server connection, verified it works by adding a table to the page above the form and added the dynamic links to the form control

Having two issues

1. dynamic values are not displaying in the control
2. Old static entries will not delete without doing so from code view

Video attached and link to page is here
