Trouble with deleting reference from Pages document

Hi everyone,

I am using the cite as you write feature in Pages, iOS.

I deleted a couple of incorrect citations from my text (by deleting the corresponding “number”, using the delete key) but the citation still shows up in my bibliography although it isn’t cited anywhere in the text anymore.

By now I am slightly desperate. Already tried to google my problem but could only find solutions for Word that do not seem to be applicable to Pages as well.

I’d be very thankful for any advice!

Cheers, Emmy
