I am relatively new to bluebeam and I am working on a set of drawings. One of the drawings has recently stopped me from editing it. I have a lot of shapes and work put into it. I can still edit the text but only if I got to edit → PDF content → edit text. All the shapes and symbols are locked into place I cant select any of them. All of the other documents I still can edit and move all the symbols. I tried clicking the unflatten button on the document but it didnt do anything.
