Autonumbered paragraphs in anchored frames are not updated in output
If you insert text boxes in your anchored frames and use a paragraph style with AutoNumber properties that display and/or increment a series building block, you may find that the numbers are not generated correctly when the graphic are rendered in your output.
For example, you may add a line to your graphics to serve as an image caption containing the position of the image in a sequence (e.g., FigureTitle). When the images are rasterized for output, the sequence variables are reset to zero each time.
This bug is referenced by defect #WWEP2478, and the timeline for a fix it not yet available.
The best workaround for this issue is to move your numbered paragraphs outside the anchored frames, into a regular text flow. You may even improve image quality by avoiding the rasterization of otherwise clean by-reference graphics.
