Hmm, so there are 2 things here to look at, the default close button text is set from the popup theme used by that popup.

Then a popup can have its own override value.

My guess is that the export with null value is being set to "" on export and thus on import is using the empty string to override the popup theme.

Might be worth modifying the output during the export to set that value to the one that should be rendered, so in this case maybe the export instead of null or '' would use the value from the current theme used by that popup instead.
