Valid to not autopulating when creating or editing articles after updating dictionary entry

On the "Valid to" dictionary entry, we used to have it set to use dynamic default that had a custom value to have all articles created and updated two years from the current date.

We decided to use the Article Validity feature so that each knowledge base could be different default Valid to entry.  We removed that customization and reverted the default value to the oob code below:

javascript: current.kb_knowledge_base ? new global.KBCommon().getDefaultValidToDateFromCurrentDate(current.kb_knowledge_base) : '';

However, since unchecking dynamic default and using the oob script when creating an article, the Valid to field is blank for new articles and does not change the date with edited articles.

I have verified that the Article Validity on each of the knowledge base is set to the correct number of days we would like for those knowledge base. But still same behavior.

Is there something else that needs to be updated as well when removing a custom Valid to default?

Thank you.
