The select at the top of the page is working fine. The one at the bottom of this modal is not (always) working. If you need to scroll down the modal in order to see it, when selecting one of the available option the page is automatically scrolled back to the top and the option is not selected.
This problem depends by the user's monitor size: this page may work fine in large monitors. If you zoom out the page, both Selects are working
This issue is also quite herratic. On my experience it happens 2/3 of the times I refresh this page
