Stubborn Calibri font in Style

When I format references, all “ibids” appear in Calibri. I have checked other threads here and followed all their suggestions. I do not use Calibri in the style nor in Word. I have checked the Word template in use and the Normal template and nowhere I find such font. When I format the references the problem affects all and only the “ibids”. The unexpected application of the Calibri font only happens when I format the references, never when I am otherwise working in Word.

It is not Calibri the stubborn font. It is “Segoe UI”… this is even more strange, since I have bever used it and is not a Windows default insofar as I know.
Any help would be greatly appreciated!

Thanks Leanne for your answer. I (believe I) have tried everything. If I change the paragraph style the font does not change, even though if I use the style inspector and reveal format it says that the fount is “(default)”, as shown below. In the endnote output style, the text for the repeated reference is “plain”, except that the “ibid” itself is set to underlined. The formatted reference in word appears with the “ibid” duly uniderlined, but the font is Segoe UI. If I unformat references, the Segoe font disappears.
