All shapes have no filling anymore


Hello everyone,

I have a strange problem. Just opened my file, all shapes that were previously filled with white colour suddenly have no fill, on all pages. This affects all my icons in buttons for example. It is virtually impossible for me to select them all together across all Dynamic Panels and pages… I don’t understand it. It is not clear to me how this happened. Is it possible to enter something like this centrally and did I do this by mistake or is this a bug? I have already partially corrected, partially not yet. I want to avoid that this happens again.

Thanks, Maila
