Apply value to all substructures doesn't work for fields that were edited as strings

[szaumoor]

This is easy to test. For example open spwi118.spl and try to change the spell icon of the first header to "test" by editing it as a string. Try to apply value to all substructures. It will say it was applied to "0" substructures, and no changes are made.

Tested in Ubuntu 24.04, latest NI release.
