I have some symbols from the ArcGIS_Explorer.style in my map. The graphics are OK like you can see in the ataachment ArcMap_correct.png.
When I export a pdf the symbols are also correct in the map but in the legend there are black rectangles instead (attachment pdf_export_error.png). I tried different settings - convert to polygon, imbedding text and so on. I tried exporting to png, emf, tiff and it is incorrect too.
I use ArcGIS Desktop 10.7.1. I exported from the same mxd some months ago and it worked great. I didn´t any ArcGIS-Update since then. Maybe a automatically Update for my Windows-System (it is not my personal PC, it is an office PC) caused this problem.
Has anyone an idea?
Thanks for your help
