We have been using the Sign Management Solution since about June 2024, no issues so far. Today I noticed that all of the default symbology has been changed to just blank white rectangles. I have gone into the Styles area of the sign layer and there is no way for me to restore the symbology of all 200+ sign types back to the symbology the solution launched with. They are all matched to the MUTCD codes and even when I set the style to unique symbols by the MUTCD attribute all I get is the option to assign manually every single icon. That would take forever and I'm not entirely sure that I'd get it 100% correct to the way it was in the beginning. I did notice that the same service in my ArcPro does still show the correct symbology. Is there a way for me to bring back the original symbology? I'm trying to avoid having to launch a second solution and merge old data with all the pictures and such. Any help would be greatly appreciated.
This is what I'm now seeing
This is what the correct symbology is
