Don't Insert Citavi Fields in Frames 

If you're using a reference number style that lists and numbers references in the order of citation, do not use frames. If you do, the Word Add-In can no longer tell the position of the references in the body of the text and the reference numbering may be incorrect.

If you previously used frames to insert images or tables across columns in a multiple column layout, replace the frames using one of the following methods:

1.Insert continuous section breaks to the left and right of the object. In Word on the Layout tab, click Breaks > Section breaks > Continuous. For each section choose the number of columns, for example two columns for text and one column for images or tables.

2.Use tables to insert images in a cell and then insert the corresponding caption in another cell. Tables also make it possible to place images next to one another.
