Fixes: #8224 1. Summary All multi-dropdowns across the application don't accept empty options because emptiness is perceived as an invalid state. 2. Solution The issue came down to the back-end and the specific string utility function that converts a string separated by `,` to an array of options. But the problem with it is that it returns `['']` for an empty string representing an emptiness. And then `['']` fails on the parser because simply `''` is not a valid option the user selected for the dropdown. So I updated the string utility function to return an empty array for cases like `'', '{}', '{ }'`, etc 3. Recording https://github.com/user-attachments/assets/071fe5d2-2123-4deb-878c-67f62d9b3431
