renaming forms

I've renamed a couple of forms, and the new names appear when hovering the mouse over the Forms tab; however, after clicking on the Script tab, the Select Form drop-down shows the old names for those forms.

The form definitions for these two forms which I renamed also show the old name. The displayname is set to the new name.
There doesn't seem to be a display name field associated with form properties.

I've created form names with spaces in the name, but it seems this is a problem when writing scripts. Is that why the old name was retained? It's confusing when using the script builder, and seeing the old names instead of the new ones for those two forms which I renamed.
