All of the custom functions in Lightroom are not working. I am not able to make custom brushes, or rename photos to a custom name. The "save current setting as new preset" option shows up in the "Effect" dropdown but once created, the custom preset is no where to be found. It is not listed with the rest of the presets. When I highlight images and go to Library > Rename photos, the "custom text" and "custom start number" is faded out, as if it is not an option to change those things. I can't type anything in, there are no text boxes. Am I missing a folder? How can I fix this?
