Paperpile "Cite" gives Greek characters

When I use “Cite” and copy it into Word, it gives Greek characters.

This seems to be because the Font in Word is changed to “Symbol”. When I change Font to Calibri, all is OK.

But why does it happen. It copies OK to Notepad.

@John_Bibby, was the “Symbol” font already selected in Word, or is it appearing on its own? It sounds like the plain-text citations are being pasted in the destination font, which is why they paste OK to notepad. Let me know if still relevant.
