XLIFF import claims "successful" but changes nothing

Hi,

I am new to XLIFF but not new to XML in general.

I have tried hand-editing a small XLF file. When I re-import it, I get the message “Translation was imported successfully” but nothing has changed in the Storyline editor.

If I use Word Doc format, it works fine.

I attached the example files I am using.

Can somebody help?

Many thanks in advance.
