The multi field values was not storing ,we select the option in the dropdown, add an item below it, remove the item below it, and then confirm by clicking the top right button, the setting is saved correctly.
Could you try the same with the OOTB WKND dropdown or core components in your AEM version? If the issue persists, it might be a product bug, and you should report it to Adobe.
If it works fine, then the issue might be related to your custom code or data attribute configuration, which you’ll need to review. Mentioning your AEM version will also help others test and provide feedback.
