Each cross-reference makes use of a hidden bookmark that encloses the cross-referenced paragraph. Unfortunately, if you add anything at the beginning of a cross-referenced paragraph (for example if you press Enter and continue typing or add a picture) that content will be included inside the bookmark and, consequently, show up in the cross-reference. To work around this, you can recreate the affected cross-references.
To avoid the problem in the future, never press Enter at the beginning of a cross-referenced item. Press Enter at the end of the previous paragraph instead.
