Does not take serialized data from ACF Pro for Elementor Pro.

I am attempting to display posts based on the value selected in the select custom field, but it does not filter the posts accordingly. Upon checking the database, I noticed that when the value is only text, it correctly filters the posts. However, after updating the post, the data becomes unserialized and the posts are no longer displayed.

This issue seems to affect newly added posts, as it still works correctly for older posts. Please assist me in resolving this issue and ensuring that the filtering functionality works consistently for both new and existing posts. Thank you
