Hi @matthewskeith
You have assumed that the data is incorrect, when in fact, the data is perfectly fine.
A checkbox can save multiple values, therefore, it will save it’s data as a serialized array.
Please leave the data as it originally was. If you want the value ‘1’ to be saved for WP_Query meta_key filtering, then please use a radio button instead of a checkbox.
The radio button, or select field will save the value as a string (un-serialized) because only 1 vaue can be saved.
Does that help?
Thanks
E
